DOS controls

Keyboard and mouse — follow the game’s own controls.

A compatible gamepad can be used after launch.

Use the game's own keyboard and mouse layout

DOS games do not share one reliable control scheme. Check the title screen or in-game help for its assigned keys.

System: Move the pointer over the game screen to reveal the player toolbar, or tap its menu button on touch devices. Use the toolbar for save and load states, fullscreen, and control settings.

Save or load game progress

Favorites bookmark this page; they do not save progress.

  1. After launching, reveal the player toolbar by moving the pointer over the game screen or tapping its menu button.
  2. Choose the save-state download option when available and keep the file.
  3. To restore it, launch the same game and choose the load-state option. Check the restored progress before replacing an older backup.

In-game saves and emulator states are different. Availability varies by game and player. Browser storage can be cleared; a downloaded backup is not cloud sync.

About Doom

Doom — DOS edition
Doom · DOS · 1995

Doom combines fast first-person combat with coloured keys, secret rooms and carefully managed health and ammunition.

Combat inside a maze of keys and secrets

Combat and exploration share the same spaces: a room may hide a key, a shortcut or a trap. Moving sideways helps avoid incoming attacks without losing sight of the enemy. Weapon choice matters because ammunition is shared between some weapons and must last through the level.

Use the locked door as a clue

A coloured locked door is a clue for your next search. Check which key is missing and use the automap to find branches you have not explored. Keeping that goal in mind helps when several corridors lead back into the same room.

Doom and Hell on Earth

These notes cover classic DOS Doom. Doom II adds different maps, enemies and the Super Shotgun. Modern source ports may also change the available controls.

Background and mechanics: Wikipedia game reference.

Secret Codes & Cheats

Check the edition and timing requirements before entering a code. Button names refer to the emulated controller; use your assigned keyboard or controller inputs.

Invulnerability (God Mode)
IDDQD

Type this letter sequence anytime during gameplay to lock health at 100% and render the Doom marine immune to all enemy projectiles, hitscans, and toxic floor slime.

All Weapons, Keys & Ammo
IDKFA

Grants all 7 weapons (including the BFG9000 and Plasma Rifle), fills ammunition reserves to maximum capacity, provides 200% blue MegaArmor, and unlocks all red, blue, and yellow keycards and skull keys.

No Clipping Mode (Walk Through Walls)
IDSPISPOPD

Disables collision detection in the original Doom v1.x engine, allowing you to walk directly through solid walls, fences, and level geometry to discover hidden rooms.

Full Automap & Monster Tracking
IDDT

Open the automap (Tab) and type IDDT once to reveal all map lines; type it a second time to display all active monsters, pickups, and projectile trajectories in real time.
