About
ONE SCREEN. TWO PERSPECTIVES.
Bring a friend into the fight. DUOM is a retro sci-fi first-person shooter with side-by-side views and independent touch controls for two players on the same device.
WATCH EACH OTHER’S BACK
Take on monsters together in local co-op. Explore industrial corridors, hunt for supplies, find keys, and fight your way to the exit.
OR HUNT EACH OTHER
Switch to deathmatch and turn your teammate into your rival. FreeDM supplies 32 arenas for head-to-head battles.
100 MAPS INCLUDED
Choose from Freedoom Phase 1’s 36 campaign maps, Phase 2’s 32 campaign maps, and 32 FreeDM arenas. Select a starting map and enemy-population difficulty from the deployment screen.
YOUR OWN CONTROLS
Each player has movement, look, fire, use, and weapon controls. Pause when you need a break and respawn to get back into the action.
PLAY SIDE BY SIDE
No second device or online matchmaking required. DUOM is designed for local play in landscape orientation; a larger screen gives both players more room.
Includes independently created Freedoom content under its open-source license. Commercial DOOM game data is not included. DUOM is not affiliated with or endorsed by id Software. Background music is not included in this release.
