Call of Duty: Warzone
Different inventory timing bugs let players use unlimited tactical stim effects and survive indefinitely in the gas. Entire matches were decided by hidden players abusing it.
Across Verdansk and later maps, vehicles, redeploy points, or terrain seams sometimes let players get below the world and shoot from safety. These spots were repeatedly patched and rediscovered.
Players parked helicopters or climbed map geometry to occupy rooftops and ledges with little intended counterplay. Some of these positions relied on collision exploits rather than normal pathing.
A notorious bug allowed multiple Juggernaut suits to be created from one event or crate sequence. Lobbies with several Juggernauts at once became effectively unbalanced.
On some builds, players could use loadouts, buy stations, or deployable cover to push cameras or hitboxes through walls for peeks and partial clips. It created unfair information advantages.
