Deathmatch Room is a room in The Binding of Isaac, added in the Repentance+ DLC.

The Deathmatch Room is exclusive to and only appears in Online Co-op.

It is a unique arena-themed room in which all players are placed after a successful co-op run.

Upon their placement in the Deathmath Room, the players' character is set to Isaac and they are given 90 seconds to fight each other.

The regular health bar is replaced with a new heart system which gradually drains, and invincibility frames are gradually reduced upon getting hit. Only one player may be the winner.

After the 90-second timer has elapsed, Fly Bombs and retractable spikes will randomly start appearing around the arena.

The health bar is refilled by one segment by picking up items and pickups that heal Red Hearts, while Soul Hearts and Black Hearts will increase the health bar by one segment.
