How to play

Classic DOOM FPS Online uses WASD keys for movement with mouse look controlling your firing angle across all 27 campaign levels. Your objective: eliminate every demon encounter to unlock exit switches and advance through increasingly hostile environments. Core mechanics include strafing circles around aggressive melee demons, timing shotgun bursts against armored Barons, and managing limited ammo pools between weapon pickups scattered throughout sprawling nonlinear maps. Secret areas hidden behind pushable walls contain soul spheres and megaspheres for health restoration. Death resets you to the level start with default weapons, punishing careless exploration and resource waste.
