Battlemode

Battlemode is the multiplayer mode in Doom Eternal. It is available on PC, PlayStation 4, and Xbox One, but does not allow cross-play. On the consoles, it requires subscription to the platform's online services (PlayStation Plus or Xbox Live Gold).

Overview
Instead of a traditional deathmatch, battlemode consists of 2-against-1 fights, pitting two player-controlled monsters against one Slayer with a fully upgraded (but not all weapons mastered) arsenal and all health/armor upgrades applied in a best-of-five format.

At the start of a round, both sides jockey for position; until the starting countdown finishes, they cannot attack but are able to move freely. It should be noted that many areas can only be reached by the Slayer, as demons cannot use portals, jump pads, or monkey bars.

The demon side wins a round by killing the Slayer, while the Slayer has to kill both demon players within 20 seconds of one another; if more time passes after the death of one demon player without the second demon player dying, the dead demon will respawn at half health.

The demon side needs to use teamwork and combine their unique abilities to gain the upper hand, while for the Slayer it is a test of skill and mobility.

Both the Slayer and the demons can choose to equip different skins (with the Slayer also getting access to weapon skins), intro animations, and victory animations in order to personalize their appearances. These can be acquired either through playing the campaign, earning XP through Battlemode matches, accumulating Slayers Club points, or completing certain out-of-game tasks.

Playable demons
Each demon has two different action sets to choose from that determine the non-unique abilities it can use, and has a play style focused on a specific role.
 * Arch-vile: Able to teleport a short distance, and specializes in area denial and movement restriction. Has the Agile and Summoner action sets.
 * Marauder: Superior mobility via double-jumping and dashing, and good at pressuring the Slayer with close range attacks. Has the Ranged and Pressure action sets.
 * Mancubus: Slow, but strong and hard to kill; also able to double jump, but cannot attack after the second jump until it lands. Has the Tanker and Support action sets.
 * Pain elemental: Can fly freely and air-dash, but has difficulty taking cover from attacks. Has the Pressure and Summoner action sets.
 * Revenant: Balanced, with the ability to fly for a short time. Has the Offensive and Defensive action sets.

Abilities
The Slayer has access to dash, glory kill, frag grenade, and flame belch, as well as most weapons and weapon mods, including the chainsaw. Demons all have access to the "block loot" ability, All demons can jump (except the pain elemental, which can instead fly). Demons have access to two different "action set" profiles each, which gives them different sets of additional abilities. The demons can summon various NPC monsters, set up healing areas, generate damaging floors, and prevent NPC monsters from dropping loot in order to deprive the Slayer of resources. Each player can only summon one monster of a given type (except of course for the soldiers who are summoned in pair); trying to summon another will kill the first one and cause it to drop loot that the Slayer can pick up. These abilities have a cooldown time between uses.
