Add this clock to the list, alongside the infinite stim glitch, the invisible player glitch, that one clock that made you visible through walls, and especially the bug that allows a player to put their full charge into the gulag bring to. The latest Call of Duty: Warzone glitch lets you parachute into the gulag while making you invincible at the same time.
It’s documented in the video above from YouTuber NTrippy, who sensibly doesn’t show how he achieved this so that other players can’t copy the feat. Usually the gulag is where dejected players get a fair fight for a chance at resuscitation, but instead of waiting for their turn in the arena, NTrippy somehow jumps out of the waiting room into the arena two rounds early. If another player tries to shoot him, he cannot be injured and will beat her to death while apologizing. “It’s too dangerous,” he says. “I need to make sure the developers know about it so they can fix it.”
It could be that this bug is only possible in the current iteration of the gulag in Warzone Season 4, which is inspired by the hijacked map from Black Ops 2 and has replaced the standoff gulag. Or maybe not. The only other information NTrippy gives in the description of the video is, “No, executions don’t work” and “It’s a time-related error. So when it’s your turn in the gulag, the error is over.”
