Knock, knock.

Call of Duty Warzone's fourth season introduced a new fast travel mechanic via the red doors.

What was seemingly just a narrative addition for the main campaign has now been implemented into Warzone and it seems like with some dire consequences.

Doors are now unsuspectingly killing players leaving many frustrated with the state of the game.

Doors Are Killing Players In Warzone

It's unsurprising to see a Warzone update go wrong like this because it seems to be a habit that the battle royale can't quite seem to shake.

With so much going on in the world of Warzone, issues are bound to pop up.

This new one is definitely one of the more bizarre ones as doors are now killing players.

Reddit user Rxelik_ posted a video of himself running into a door and being instantly downed.

It's worth pointing out that this is an inaccessible door, but if you're caught in an engagement that back you into a corner you could find yourself unfairly killed.

It's being speculated this issue has occured as a result of the implementation of red doors.
