PhD Slider, fully known as PhD Slider Soda, is a Perk-a-Cola featured in Call of Duty: Black Ops 4 and Call of Duty: Black Ops Cold War Zombies. It is the successor to PhD Flopper, a perk previously featured in Call of Duty: Black Ops and Call of Duty: Black Ops II.

Overview[]

Call of Duty: Black Ops 4[]

"Slide to build up a charge. Once fully charged, slide into an enemy to trigger an explosion. Gain full resistance to self-inflicted explosive damage and partial resistance to enemy explosive damage."
— Description

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[]

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

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.

Tiers[]

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.

Trivia[]

  • Despite going by a different name, PhD Slider re-uses the original PhD Flopper jingle, which erroneously mentions the latter's name and diving to prone in spite of PhD Slider's sliding mechanic.
  • According to the nutrition facts on the PhD Slider can, one can of PhD Slider contains: 238.02 calories, 70g of total fat, 1800g of sodium, 90g of total carb, 70g of sugars, and 30g of protein.
  • According to the ingredients list on the PhD Slider can, PhD Slider contains the following: castor oil, nitroglycerin, powdered graphite, blasting cap extract, and distilled banana peel.
  • At some point, PhD Slider was going to have its Black Ops 4 logo in Black Ops Cold War before being changed to resemble the original PhD Flopper logo. Files still remain of a ping icon for PhD Slider bearing the original logo.
  • It is possible to get the points for both meleeing and sliding into a zombie while only killing one zombie provided the player times it correctly and has a strong enough melee weapon.
  • None of the operators make a call out for PhD Slider in Black Ops Cold War.
