Last week the new update of Call of Duty: Warzone which introduced the 4 season, with lots of new content. It also seems to have introduced a very bad door, so bad that you just have to get close to it to die, as you can see from the post published on Reddit.

This is almost certainly a bug but some players have also suggested that it could be related to the red doors that have started popping up in Warzone since the last major update. However, everything seems quite unlikely and we are pretty sure that the door will be patched soon, you just have to wait, in the meantime stay away from it.
