Cold War Zombies Season 6: PhD Flopper will become PhD Slider - New Effects inbound

Will this perk even work with Black Ops Cold War's mechanics?

what does phd mean in phd flopper

Season 6 will be the grand finale for Black Ops Cold War Zombies - and it's going out with a bang!

In Season 6 we'll be getting a new round-based Zombies map called "Forsaken", and there's a new Perk-a-Cola on the way as well!

Table of Contents

Latest: phd slider tier upgrades revealed, full reveal - phd flopper is phd slider, now, new perk teaser - phd flopper is coming, release date - when does the season 6 update drop.

Here's everything we know about PhD Slider, the new perk, and why it isn't called PhD Flopper anymore...

Treyarch have released the Season 6 patch notes for Black Ops Cold War , and with it comes some more information on the new PhD Slider Perk for Call of Duty Zombies.

Here are the new PhD Slider upgrades unlocked at each tier of the skill:

  • Base Ability - Sliding into enemies triggers an explosion. The size and damage increase the further you slide before impact
  • Skill Tier I - Immunity to environmental damage while sliding
  • Skill Tier II - Increased slide duration
  • Skill Tier III - Immunity to self-inflicted explosive damage
  • Skill Tier IV - Increased slide speed
  • Skill Tier V - Falling from a large height will trigger an explosion - the size and damage increases the higher you fall

As you upgrade PhD Slider it will become even more lethal, which will add a ton of fun to the new Zombies content coming in Season 6!

We were a bit confused when we saw PhD Flopper was due to return - because Black Ops Cold War doesn't have a diving mechanic - and now we know what the deal is.

PhD Flopper is being called PhD Slider from here on out. It'll work the same way, but just with sliding instead! Here's the basic effect of PhD Slider :

" Sliding into enemies triggers an explosion. The size and damage increase the farther you slide before impact."

You will also be able to upgrade PhD Slider with Aetherium Crystals and unlock self-inflicted damage immunity and bigger explosions. More on that to come soon...

Ahead of an official announcement, Treyarch revealed the following "Twitter Voice" on their official Twitter channel. It's a short clip of some Perk Machine audio with the icon associated with Black Ops' PhD Flopper perk. You can check it out below:

A lot of people - and one account called DailyPhDFlopper - are excited to see this iconic perk make a return, however... It does raise a few questions on how it will work.

Black Ops Cold War doesn't have a "dive feature" - rather, you slide in Black Ops Cold War when you hold Crouch. We don't know whether this Perk will include a new "dive feature" just yet, but Treyarch should confirm how it works soon.

Traditionally, PhD Flopper is a perk that negates self-inflicted damage - mainly through explosions - and allows the player to "dive" to create a small explosion upon landing. Something to remove self-inflicted damage would be useful in Black Ops Cold War Zombies - but what about the diving?

Black Ops Cold War's new Zombies map is due to launch alongside the rest of Season 6's content at the following times:

  • 21:00 October 6th - PST
  • 23:00 October 6th - EST
  • 04:00 October 7th - BST

At the moment, we know that the new Zombies map is called "Forsaken" and that Alex Mason is set to be the Season 6 Battle Pass Operator . Warzone's Verdansk '84 is also going to undergo a few drastic changes ahead of Vanguard's release. You can see it all in the Cinematic Trailer below:

Wondering how to get PHD Flopper in MW3 Zombies ? Right in the first week, Sledgehammer Games asked players to find the elusive perk and get 30 kills with it. 

This can seem confusing to some players so read on for a comprehensive guide that details how to get this item and its special effects. If you want to learn more about all the perks in MW3 Zombies like Jugger-Nog, Deadshot Daquiri, and Stamin-Up, we’ve got you covered. And if you want to play with friends, check if MW3 Zombies supports split-screen .

Get the PHD Flopper for free in MW3 with our top two methods

The PHD Flopper is a perk that grants immunity to fall damage and a special explosion when the player dives to prone. Diving to prone triggers an explosion that scales with the height of the jump. Want to minimize the time and effort for getting the PHD Flopper explosions? A free perk is a rather tempting proposition, especially since this will allow you to focus on tougher missions and contracts. Read on for our two methods of obtaining this item for free:

  • Craft a PHD Flopper with its Schematic for free – Some contracts or mission rewards can offer you the PHD Flopepr Schematic. Exfil with this reward and you’ll be able to create it before your next Zombies playthrough. Just remember that doing so starts a cooldown, ensuring that you can’t spam this ability. 
  • Jump into the pool from the Shahin Manor roof to get this perk – This secret location lets you get the PHD Flopper perk for free. Jump into the pool near Mister Peeks and you’ll activate a Reward Rift with this perk.

PHD Flopper’s damage scales with the height of the jump

Diving into prone from tall buildings let you deal even more damage to enemies. Use this against armored zombies and mercenaries.

Find the PHD Flopper in Modern Warfare 3 in three ways

In MW3 Zombies, the PHD Flopper can be found in loot caches, Reward Rifts after contracts, and from vendors scattered across the map. Here’s a clearer explanation of how to get the PHD Flopper in MW3 Zombies:

  • Purchase it from a perk machine vendor for 2000 Essence – On the Tac Map, look for a nuclear sign. Hover over it and you’ll be able to check which perk this vendor sells. Find one that sells the PHD Flopper, head over there, and purchase it. Remember to exfil in MW3 Zombies if you want to use this perk later on.
  • Find a contract that offers the PHD Flopper as a reward – As you complete contracts in the MW3 Zombies map, you gain powerful rewards. Look out for higher-value contracts for a chance at this perk.
  • Get the PHD Flopper perk from a loot cache – The odds of this are pretty rare but some loot caches offer access to perks. Mercenary Caches can be found in Mercenary Stronghold scattered around the map. You can also find caches in Aether Nests. One particularly rewarding activity is destroying the mercenary convoy in MW3 Zombies .

Is the PHD Flopper worth the effort and how to maximise its potential

While it can take a while to acquire this perk, the explosions triggered by diving to prone is a great offensive tool. There’s a trick to making the most of it. Sure, you can just dive to prone wherever you are in earlier threat levels. But later on, zombies gain more health.

In that case, you can still clear large waves of enemy forces just by diving from tall buildings. This is because the damage you trigger is scaled to the height that you jump from. And don’t worry about dying from a steep fall as this perk grants immunity to fall damage. 

That covers the PHD Flopper in MW3 Zombies. Check out our best MW3 loadouts if you want more straightforward paths to success in Call of Duty’s multiplayer lobbies. And if you’re considering an expensive upgrade, check if the MW3 Vault Edition is worth it .

Is the PHD Flopper good in MW3 Zombies?

The PHD Flopper’s explosions are a good situational tool.

Can you purchase any perk from a vendor in MW3 Zombies?

No, a vendor will only offer one perk picked at random.

A Perk-a-Cola released alongside Stamin-Up in the zombies map pack Ascension. It allows the player to become immune to explosive and falling damage.

Summary short summary describing this thing..

No recent wiki edits to this page.

PhD Flopper is a perk that makes players immune to self-dealt damage. It also makes players immune to fall damage. If the player "dolphin dives" it creates a small explosion damaging and killing (in early rounds) all zombies in a set radius. The perks effectiveness is less on Call of Duty: Black Ops Zombies because the player cannot jump. It costs 2000 points.

PhD Flopper

  • Edit source
  • View history

For the perk's successor, see PhD Slider .

PhD Flopper is a Perk-a-Cola Machine that appears in the Call of Duty: Black Ops Nazi Zombies maps Ascension , Call of the Dead , Shangri-La ,  Moon , and secretly on Die Rise  and Mob of the Dead , as well as in Cell Block and  Origins  from the WunderFizz Machine . After the player buys the perk, all damage that the player could cause to themselves by explosives and fall damage is nullified. It completely removes splash damage, making the Ray Gun, Mustang & Sally, Matryoshka Dolls or any explosive good for getting out of tight situations, and adds a miniature explosion whenever a player with the perk dives to prone. However, the explosion only occurs if you dive high enough that you would normally recieve fall damage. It instantly kills all zombies within the small radius of the explosion in the earlier rounds and makes crawlers in the later rounds. Any kill you get from the explosion is only 50 points like all the other explosives.

A Persistent Upgrade on Buried is based off of PhD Flopper, excluding the negating effects of fall damage and overcooked grenades.

Due to the Sliding move replacing the "Dolphin Dive" move in Black Ops III , the perk is completley absent. Substitute Gobblegums serve as replacements, which are Danger Closest, and Slaughter Slide. In the Black Ops III version of Ascension , Shangri-La , Moon , and Origins , it was replaced by Widow's Wine .

  • In the Die Rise map on Black Ops 2, PhD Flopper is secretly located on the 3rd level when going down the broken cargo elevator (at the beginning).

Treyarch Confirms PhD Flopper As Call of Duty: Black Ops Cold War Zombies’ Final Perk

Black Ops 6 Has Put All The Pieces in Place For a Sequel to Call of Duty Zombies' Wackiest Map

This diablo 4 season 4 class build is perfect for casual players, call of duty: black ops 6 may have bad news for playstation gamers.

For some time now, Call of Duty: Black Ops Cold War players have known that the next round-based map will be the game’s last. They have also known that the final Survival location will feature a new perk, with Treyarch confirming that a classic beverage is returning in Call of Duty: Black Ops Cold War .

Back near launch, the lineup of additional Zombies perks leaked . Both Tombstone and Mule Kick were on this list, with fans able to listen to their jingles long before they became purchasable in the game. However, Double Tap did not end up coming, as the incredibly strong perk would have thrown off balancing based on Treyarch’s comments. As such, it was replaced with Death Perception, a Call of Duty: Black Ops 4 perk that is particularly useful for Outbreak players.

RELATED: Call of Duty Black Ops Cold War Players Want Randomized Finishers

Following this Death Perception change , some were wondering if PhD Flopper would be swapped out with another perk as well. Fortunately, that is not the case. Treyarch not only changed its Twitter profile picture to the perk’s instantly recognizable logo, but the developer also posted its iconic jingle in a separate Tweet. While this is obviously exciting, it is interesting that the perk is using its original design and song, as that would imply functionality similar to its first appearance.

The issue with PhD Flopper is that, as its name suggests, it relies on players diving from large heights to trigger an explosion. Because of this, the perk could not fill its original role in games like Call of Duty: Black Ops 3 and Black Ops 4 . Once Treyarch swapped out dolphin dives for sliding, one of the main features of the perk went away. While it could retain the explosive invulnerability, “flopping” was no longer possible. As such, the perk was not seen in Black Ops 3 and was reworked into the less interesting PhD Slider in Black Ops 4 .

With this in mind, it will be interesting to see how it functions. While it is possible that it features a flopping ability just like the original, it seems unlikely that Treyarch would add a whole new mechanic for one perk. As such, Call of Duty: Black Ops Cold War players may see it functioning like PhD Slider, but with the classic jingle and design used to evoke some nostalgia. With 5 perk tiers to work with, though, an upgraded version of the perk could end up being very powerful.

With more being shown from Season 6’s Forsaken map later today, players may only need to wait a few hours before they get their answers on how exactly PhD Flopper works. Based on the reaction so far, though, the Zombies community is very happy to see it back.

Call of Duty: Black Ops Cold War is available now on PC, PS4, PS5, Xbox One, and Xbox Series X.

  • It does a number of things. Firstly your can't harm yourself with explosive weapons, including the raygun. Secondly you have no fall damage meaning you can jump from any height without hurting yourself. Finally if you prone dive off a raised position when you land a small explosion will take place, killing zombies around you. Useful for when you run out of ammo :) NoNamesAvalible - 13 years ago - report 2   0
  • It means that you can't harm yourself when you fall from a great height or hit yourself with your own grenades, semtex, scavenger, raygun etc. This perk was in Ascension as well as Call of the Dead. Joshua547 - 13 years ago - report 0   0
  • PhD Flopper is a 2000 point perk. You take no fall damage when you dive you will make an explosion. Also you will take no explosive damage, Ray gun, Frag, Semtex, this perk is also on Ascension by the MP5K lander. xPUMAgt1232 - 13 years ago - report 0   0

Treyarch teases return of PhD Flopper, new Aether Remote-Controlled Device in Call of Duty: Black Ops Cold War Zombies map Forsaken

Image of Jalen Lopez

Call of Duty: Black Ops Cold War Zombies players have a lot of exciting content on the horizon, including the likely return of PhD Flopper and a new Aether Remote-Controlled Device. 

It’s been a good week for Zombies players. Yesterday, Treyarch revealed the final Black Ops Cold War Zombies map, Forsaken , which concludes the opening chapter of the Dark Aether storyline. But Treyarch saved two exciting pieces of information for today, including the likely return of a popular perk. 

🎶 pic.twitter.com/fy8HJBJTWO — Treyarch Studios (@Treyarch) September 29, 2021

Treyarch posted a short snippet of the original PhD Flopper perk theme that first appeared on Ascension in Black Ops 1. This iconic perk negates self-inflicted damage and allows plates to create a small explosion when they dive to prone from an elevated position. The perk became less effective the longer a game lasted, but it was still an excellent and entertaining option in early rounds. 

PhD Flopper appeared in several maps across multiple games but was eventually replaced with PhD Slider in Black Ops 4 . The perk has yet to appear in Cold War Zombies, but the teaser indicates it might be available on Forsaken. Cold War has a slide mechanic instead of a dive, though, so it’s unclear exactly how PhD Flopper will work if it’s added to the game or if PhD Slider will return. 

Approved by Dr. Hugo Jager: the Aether Remote-Controlled Explosive Device. #Forsaken pic.twitter.com/SDCOkFqb4H — Treyarch Studios (@Treyarch) September 29, 2021

The other teaser posted today shows an approved blueprint of an Aether Remote-Controlled Explosive Device, which is similar to the iconic RC-XD killstreak. It’s unclear how players will unlock and use this item on Forsaken, but it could add another exciting layer to the upcoming map. 

Forsaken will be released on Oct. 7.

How to Complete PHD Flopper Explosions Weekly Challenge in Modern Warfare 3 Zombies

Home » Call of Duty MW3 » PHD Flopper Explosions Weekly Challenge in Modern Warfare 3 Zombies

The first week of Modern Warfare 3 launch gave us a weekly challenge that demands players get 30 kills with PHD Flopper Explosions in MW3 Zombies mode. This new game mode brought in several new mechanics and you might be confused by what you’re supposed to do here. One of them are this soda drinks you can find in loot caches or buy at special festival shops. Once you consume these drinks you’ll get a special buff. PHD Flopper is one of those drinks. Let me quickly explain what you need to do to finish your weekly or daily challenge involving PHD Flopper explosions in Modern Warfare 3 Zombies.

How to do 30 Zombie Kills With PHD Flopper Explosions?

PHD Flopper is a buff drink that, when consumed, triggers and explosion when you dive to prone. What this means is that you have to run and press and hold crouch, by default, while running to dive into the prone stance. If you drank the PHD Flopper beforehand this will trigger an explosion that damages surrounding enemies. PHD Flopper explosions increase in strength the higher you fall. This means that if you dive to prone from a top of the building the explosion will be massive. Also, while under the influence of this buff, you get no fall damage while diving and your explosion does not affect you.

I did this challenge by attracting the attention of a bunch of zombies and climbing on top of a nearby wall. I would than run on top of the wall and press crouch facing the zombie mob that would be bellow me. I would dive into prone among them and explode. It took several tries to get enough to complete the challenge. Do note tthat as soon as you land and explode you need to get up and start running. Otherwise, those zombies you didn’t kill will rip you to shreds.

How to get the PHD Flopper Can in Modern Warfare 3 Zombies?

You can find PHD Flopper can in finished contract reward portals or in rare loot caches. You can also get it as a reward from one of the first MW3 zombies missions. The easiest way though is to look at the map for an icon with a nuclear sign on it. When you hover over it it should say PHD Flopper. This is a special vendor kiosk that you can buy the buff from for that single deployment. I believe it costs 2000 aether. If you get this soda can as a drop before this daily you might want to exfil with it. This will keep it in your acquisitions and you can bring it with you to a deployment once PHD Flopper Explosions daily/weekly challenge happens again.

Similar buff was obtrainable in “Call of Duty: Black Ops Cold War”. It was a PhD slider you got from a perk machine.

Overview [ ]

Call of duty: black ops 4 [ ].

PhD Slider, when purchased, allows players to create an explosion that can kill zombies by sliding into them, as well as reduce explosive damage the player receives. In order to create an explosion, the player must first charge up the perk, which can be achieved by sliding. Once a charge is ready, the perk icon will begin to pulsate and flash. When the perk is initially purchased, the player will already have a full charge ready.

When PhD Slider is set as the "Modifier" perk and the player has all of their other perks, the perk will allow the player to have increased sliding distance, as well as having immunity to trap damage whilst sliding. Players will also gain increased explosive damage on enemies when entering a slide from a greater height.

In Create-A-Class , PhD Slider is unlocked at Level 42 as the last unlockable Perk, and can be applied to the player's Perk loadout to appear in any map. It can also be obtained randomly through the use of Secret Sauce if available and through a myriad of other Perk-based rewards and items within the game.

On January 15th, 2019 with Patch 1.11, PhD Slider was buffed, allowing players to take zero self-inflicted explosive damage. However, the damage reduction for enemy explosive attacks has been reduced from 80% to 50%.

Call of Duty: Black Ops Cold War [ ]

PhD Slider was released with the Season Six content update for Call of Duty: Black Ops Cold War on October 7th, 2021. It is available in Der Wunderfizz on all maps, and is featured within its own perk machine on Forsaken , which reimagines the original PhD Flopper's perk machine.

PhD Slider allows the player to generate an explosive burst of Aetherium energy upon sliding into a zombie. Unlike its Black Ops 4 iteration, it does not require players to charge it up. Instead, the size and damage of the explosion are dependent on the distance the player slid before impacting a target. Additionally, in order to have immunity from self-inflicted explosive damage, the perk must be upgraded to Tier III.

In Call of Duty: Black Ops Cold War , PhD Slider can be permanently upgraded with the use of Aetherium Crystals , yielding a variety of new additional bonus effects alongside its base ability.

  • Tier I - Immunity to environmental damage while sliding.
  • Tier II - Increased slide duration.
  • Tier III - Immunity to self-inflicted explosive damage.
  • Tier IV - Increased slide speed.
  • Tier V - Falling from a large height will trigger an explosion. The size and damage increase the higher you fall.

Locations [ ]

  • Die Maschine - Can be purchased from Der Wunderfizz. It can also be obtained as a Legendary reward from the Trials system.
  • Zombies Onslaught - Can be randomly acquired from a Random Perk power-up, as well as dropped from elites.
  • Firebase Z - Can be purchased from Der Wunderfizz. It can also be obtained as a Legendary reward from the Trials system.
  • Outbreak - Can be purchased from Der Wunderfizz or randomly acquired from a Random Perk power-up. It can also be obtained as a Legendary reward from the Trials system.
  • Mauer der Toten - Can be purchased from Der Wunderfizz, obtained as a Legendary reward from the Trials system, and randomly rewarded from the Nightclub easter egg.
  • Forsaken - In the Observation Tower, to the left of the zipline leading down to the Burger Town Rooftop. It can also be purchased from Der Wunderfizz and obtained as a Legendary reward from the Trials system.

How to Get the PHD Flopper Schematic in MWZ

How to Get the PHD Flopper Schematic in MW3 Zombies

Image of Christian Bognar

The PHD Flopper is a helpful perk in Modern Warfare 3 Zombies that can deal with crowd control damage as it explodes and hits every enemy nearby. If you want to permanently unlock PHD Flopper and gain easy access to this powerful perk, you will want to find the Schematic.

This guide will walk you through how to get the PHD Flopper Schematic in MW3 Zombies, as there are specific steps one must take to unlock it officially.

Unlocking the PHD Flopper Schematic in MW3 Zombies

Players can get the PHD Flopper Schematic in MW3 Zombies by completing Contracts in a Tier 2 Zone . Completing contracts within these zones makes it possible for the PHD Flopper Schematic to appear as a reward, although it is not guaranteed.

If you complete a contract within a Tier 2 Zone and unfortunately don’t receive the PHD Flopper Schematic as a reward, then you’ll have to continue to complete contracts until you do. The good news is that it doesn’t matter which contract you complete; it’s just mandatory that it takes place within a Tier 2 Zone to unlock the PHD Flopper.

Best Contracts to Complete for Schematics

The best contracts to complete while trying to unlock a Schematic in a specific zone are the ones that take little time to complete . Focusing on short contracts will allow you to complete them in quick succession, increasing your chances of obtaining the Schematic in mind. The quickest contracts are Eliminate the Bounty, Outlast, and Deliver Cargo .

I recommend focusing on Deliver Cargo contracts as they’re the quickest to complete and relatively easy. The objective of the Deliver Cargo contract is to take an armored vehicle to a specific location, something that should take little time. The location is usually not far at all from where you accept the contract, meaning it’s a short drive.

Remember, make sure that the contract takes place within a Tier 2 Zone to create the chance of getting the PHD Flopper Schematic as a reward!

If you want to find other Schematics in MW3 Zombies, we have you covered with guides on the Attack of the Fanboy site. Check out our guides on how to get the Deadshot Daiquiri , Epic Aether Tool , and Speed Cola Schematics.

Congratulations; you’ve finished your research! Time to write your PhD thesis. This resource will take you through an eight-step plan for drafting your chapters and your thesis as a whole.

Organise your material

Before you start, it’s important to get organised. Take a step back and look at the data you have, then reorganise your research. Which parts of it are central to your thesis and which bits need putting to one side? Label and organise everything using logical folders – make it easy for yourself! Academic and blogger Pat Thomson calls this  “Clean up to get clearer” . Thomson suggests these questions to ask yourself before you start writing:

  • What data do you have? You might find it useful to write out a list of types of data (your supervisor will find this list useful too.) This list is also an audit document that can go in your thesis. Do you have any for the “cutting room floor”? Take a deep breath and put it in a separate non-thesis file. You can easily retrieve it if it turns out you need it.
  • What do you have already written? What chunks of material have you written so far that could form the basis of pieces of the thesis text? They will most likely need to be revised but they are useful starting points. Do you have any holding text? That is material you already know has to be rewritten but contains information that will be the basis of a new piece of text.
  • What have you read and what do you still need to read? Are there new texts that you need to consult now after your analysis? What readings can you now put to one side, knowing that they aren’t useful for this thesis – although they might be useful at another time?
  • What goes with what? Can you create chunks or themes of materials that are going to form the basis of some chunks of your text, perhaps even chapters?

Once you have assessed and sorted what you have collected and generated you will be in much better shape to approach the big task of composing the dissertation. 

Decide on a key message

A key message is a summary of new information communicated in your thesis. You should have started to map this out already in the section on argument and contribution – an overarching argument with building blocks that you will flesh out in individual chapters.

You have already mapped your argument visually, now you need to begin writing it in prose. Following another of Pat Thomson’s exercises, write a “tiny text” thesis abstract. This doesn’t have to be elegant, or indeed the finished product, but it will help you articulate the argument you want your thesis to make. You create a tiny text using a five-paragraph structure:

  • The first sentence addresses the broad context. This locates the study in a policy, practice or research field.
  • The second sentence establishes a problem related to the broad context you have set out. It often starts with “But”, “Yet” or “However”.
  • The third sentence says what specific research has been done. This often starts with “This research” or “I report…”
  • The fourth sentence reports the results. Don’t try to be too tricky here, just start with something like: “This study shows,” or “Analysis of the data suggests that…”
  • The fifth and final sentence addresses the “So What?” question and makes clear the claim to contribution.

Here’s an example that Thomson provides:

Secondary school arts are in trouble, as the fall in enrolments in arts subjects dramatically attests. However, there is patchy evidence about the benefits of studying arts subjects at school and this makes it hard to argue why the drop in arts enrolments matters. This thesis reports on research which attempts to provide some answers to this problem – a longitudinal study which followed two groups of senior secondary students, one group enrolled in arts subjects and the other not, for three years. The results of the study demonstrate the benefits of young people’s engagement in arts activities, both in and out of school, as well as the connections between the two. The study not only adds to what is known about the benefits of both formal and informal arts education but also provides robust evidence for policymakers and practitioners arguing for the benefits of the arts. You can  find out more about tiny texts and thesis abstracts on Thomson’s blog.

Write a plan

You might not be a planner when it comes to writing. You might prefer to sit, type and think through ideas as you go. That’s OK. Everybody works differently. But one of the benefits of planning your writing is that your plan can help you when you get stuck. It can help with writer’s block (more on this shortly!) but also maintain clarity of intention and purpose in your writing.

You can do this by creating a  thesis skeleton or storyboard , planning the order of your chapters, thinking of potential titles (which may change at a later stage), noting down what each chapter/section will cover and considering how many words you will dedicate to each chapter (make sure the total doesn’t exceed the maximum word limit allowed).

Use your plan to help prompt your writing when you get stuck and to develop clarity in your writing.

Some starting points include:

  • This chapter will argue that…
  • This section illustrates that…
  • This paragraph provides evidence that…

Of course, we wish it werethat easy. But you need to approach your first draft as exactly that: a draft. It isn’t a perfect, finished product; it is your opportunity to start getting words down on paper. Start with whichever chapter you feel you want to write first; you don’t necessarily have to write the introduction first. Depending on your research, you may find it easier to begin with your empirical/data chapters.

Vitae advocates for the “three draft approach” to help with this and to stop you from focusing on finding exactly the right word or transition as part of your first draft.

  12. A trivial question about PhD Flopper : r/CODZombies

    A trivial question about PhD Flopper. Question. Was the name originally meant to be read as "Dr. Flopper"? I've always thought that rolled off the tongue way better, and kinda sounds like they would be playing off Dr. Pepper, which matches the soda theme. The original machine also had it written as Flopper PhD which also works out.

  18. PHD Flopper Explosions Challenge in Modern Warfare 3 Zombies

    PHD Flopper is a buff drink that, when consumed, triggers and explosion when you dive to prone. What this means is that you have to run and press and hold crouch, by default, while running to dive into the prone stance. If you drank the PHD Flopper beforehand this will trigger an explosion that damages surrounding enemies.

  19. Is PhD Flopper ACTUALLY a good perk or is it all just nostalgia?

    I'd happily say that PhD Flopper is a decent perk, especially on BO1 Ascension, however outside of that I personally believe it is pretty pointless. Fun but I wouldn't call it a crutch. It's useless when you don't have explosive weapons and when you get to rounds where those weapons don't kill.

  24. PHD Slider > PHD Flopper. Change my mind : r/CODZombies

    Plus unlike bo1 you have great weapon choices in bo4 making slider useless when the player would use any other weapon with no splash. Really phd slider is the unnecessary version of phd flopper. The only way it would have been a God perk like phd flopper was if the modefier allowed the infinite slide like in bo3.
