DOOM (1993) (PC) Walkthrough, Secrets & Cheat Codes
DOOM is about movement and ammo discipline, not standing still. The winning habit: keep moving (strafe and circle-strafe), switch to the Shotgun for close packs and the Rocket Launcher for groups, and always hunt the secret walls (they're often slightly off-color or have a different sound when shot). On PC the classic codes make practice painless.
1Game Basics
The FPS that defined the genre: blast demons through maze-like bases.
2Core Gameplay
You carry a weapon roster (Pistol → Shotgun → Chaingun → Rocket Launcher → Plasma → BFG). Health and armor are king; secrets hide better gear and shortcuts. Circle-strafing keeps you alive.
3Step-by-Step Walkthrough
- Always keep moving; strafe around enemies to dodge fire.
- Use the Shotgun up close and the Rocket Launcher on clusters.
- Look for secret doors: walls that are a shade different, or that emit a click when you shoot them.
- Find the BFG-9000 in later levels for bosses.
- On PC, the original cheat codes let you practice any level safely.
