No, though it helps with context. DOOM Eternal is a direct narrative sequel to Doom (2016) and continues its story, characters, and setting. The game can be followed without having played the previous entry, but playing Doom (2016) first gives a clearer picture of the Slayer's backstory and the events leading into Eternal.

Battlemode is DOOM Eternal's multiplayer mode, developed entirely in-house by id Software. It pits one player controlling a fully armed Doom Slayer against two players controlling demons, fighting across a best-of-five round match. It replaces the external multiplayer used in Doom (2016).

No. The standard purchase includes the full single-player campaign and Battlemode only. The Ancient Gods Part One and Part Two campaign expansions, along with all cosmetic packs, are included in the Deluxe Edition or sold separately.

DOOM Eternal builds significantly on its predecessor with a faster, more aggressive resource management system tied to Glory Kills, incineration, and chainsaw executions. Mobility is greatly expanded with double dashes, monkey bars, and wall climbing, and the enemy roster grows to over 40 types with redesigned classics and new threats like the Marauder. The story also receives a much heavier focus, with deeper lore and a larger emphasis on cinematic storytelling than the previous reboot entry.
