Another day, another game-breaking glitch in Call of Duty: Warzone. It wasn’t quite the infamous stim glitch, but the end result was similar, as this time players found an exploit that allowed them to create unbreakable gas masks. Thankfully, this particular method has now been patched out by Raven.
In your average game of Warzone, masks are supposed to degrade when you sit outside the ring, eventually breaking so that you start taking damage from the gas (and die). Some players figured out a way to glitch the masks to prevent them breaking at all, allowing them to stay far outside the ring and avoid any final battles. The method of doing this was apparently quite fiddly, and involved deliberately killing yourself at the right time (then winning a Gulag and picking up a gas mask).
Thankfully Raven has already issued a fix for this exploit, which should hopefully prevent people from camping out in the gas. Until another cheating method is discovered, perhaps.
