HELL FREEZES OVER in DOOM: The Dark Ages | Revelations, an all-new campaign expansion that unleashes a brutal new chapter of the Slayer’s saga.

Wounded and betrayed, the Slayer is thrust into a merciless purgatory only escapable by confronting haunting truths and forging new strength with the help of a mysterious ally. He must ascend from the prison of his mind and fight an abomination of the gods to set his followers on the path to freedom.

Featuring new levels with deeper puzzles, new demons, and new mysteries, Revelations opens up a whole new dimension of combat. The all-new deadly Chain Spear offers returning slayers a uniquely satisfying combat system – one that rewards mastery with enhanced power and mobility.

Also included is the highly anticipated Ripatorium 3.0, adding DLC content (3 new maps, new demons, and fully upgraded new weapons) plus deeper customization, improved pass code generation, and saving + loading personal presets.
