Call of Duty: Modern Warfare
- "Killing players immediately starts health regeneration. Capturing and holding objectives will increase your health regeneration rate."
- — Create-A-Class description
Quick Fix removes the user's health regeneration delay each time they score a kill, and doubles health regeneration rate whenever the user are carrying, capturing, or holding an objective.
Before the 1.14.0 Perk rebalancing update, the regeneration delay after a kill was not completely removed but only reduced to 3 seconds. This was possibly changed to make the perk even more viable for an aggressive play style.
Call of Duty: Mobile

- — Description
Quick Fix returns in Call of Duty: Mobile as a Tier 2 perk. It was added during the Season 8 The Forge update.
It regenerate the health after kills with gun, melee, or Combat Axe. Capturing and holding objectives also increases the health regeneration.
