There will be six maps at launch for the mode.

Between each round, players will be able to choose miscellaneous upgrade perks, such as one seen in the trailer that makes your Flame Belch drop more armor. The winner of the round is determined by the demons killing the Doom Slayer, or the Doom Slayer taking down both the demons in a timely manner. When one demon is downed, there's a 20 second respawn timer, at which point the deceased demon will spawn back in at half health. During a video outlining the new mode, the narrator insists the two demons must work together to survive because if Doom Slayer gets one alone, it could spell the end. They can lay traps around the map for Doom Slayer, or they can spawn other demons to distract Doom Slayer. On paper, this sounds a bit unfair, but in-game, the demons are stronger than they may initially appear. In it, one player is the Doom Slayer, while the other two players are demons.

Doom Eternal is getting an all-new multiplayer mode called Battlemode, which was initially revealed back at E3 2019.
