From Bethesda Softworks:
Dawn of the Machine features 19 all-new maps across a cohesive campaign, a brand-new soundtrack, hidden secrets, a dedicated episode hub, an all-new deathmatch map, and three new achievements to unlock (on applicable platforms). Players will face deadly new variants of familiar enemies, discover powerful weapon variants inspired by classic Quake expansions, and unravel a unique looping campaign structure that unlocks new paths, encounters, and rewards with each return.
In Dawn of the Machine, Ranger finds himself trapped in a dimension of endless illusion and must track down the mysterious Nightmare Machine to finally break free. Along the way, players will shift between dimensions, uncover hidden secrets, and face unpredictable encounters where reality itself is constantly changing.
