DOOM

The game uses a first-person perspective as players explore interconnected stages, activate switches, collect keycards, and locate level exits. Core actions include moving, turning, shooting, switching weapons, and dodging enemy attacks. Weapons include fists, chainsaw, pistol, shotgun, chaingun, rocket launcher, and plasma rifle. Progression is stage-based across multiple episodes, and some versions include multiplayer support for cooperative and versus play.

Learn level layouts and keycard locations early to avoid getting trapped or wasting health. Use cover and controlled shots against distant enemies, while the shotgun is ideal for close and mid-range fights. The rocket launcher is powerful but dangerous in tight rooms. Since ammo and health pickups are limited, avoid unnecessary damage and save stronger weapons for heavy encounters later in each episode.

Tips and tricks

• Memorize door colors and switch locations to reduce backtracking.
• The shotgun is efficient for most regular encounters.
• Strafing is safer than simply backing away from projectile attacks.
