A vigilante Call of Duty: Warzone player has taken it upon themselves to crack down on under-the-map cheaters.

As we reported last week, Call of Duty: Warzone players found a way to get under the new Verdansk ’84 map just two days after it came out.

The existence of the well-known and easy-to-perform glitch means players are being killed by enemies they can’t see at a few points of interest on the map, including Stadium and Airport.

But this glitch is also possible on Rebirth Island, the scene of the below clip.

One way players are getting out of bounds is by parking a vehicle in a specific spot on the map, then exiting. For some reason, players then clip through the wall into a place they shouldn’t be. Players are then able to escape from under the map by using the vehicle once again, like a door between the two virtual worlds.
