Strife: Quest for the Sigil, often shortened to Strife, is a first-person shooter video game developed by Rogue Entertainment and published by Velocity, based on the Doom engine from id Software. Strife added some role-playing game elements and allowed players to talk to other characters in the game's world.
The Original Strife: Veteran Edition was released on Steam on December 12, 2014.
The world is a comprehensive environment, not divided into levels like most other 3D shooters of the time. Instead, the player travels from a central hub-like area in the city between various levels which will stay the same as when the player left them. It shares this feature with another Doom engine title: Hexen: Beyond Heretic by Raven Software.
