Doom (32X Version)

Game Overview

Doom is a seminal first-person shooter released by id Software in 1993 that laid the foundation for the modern FPS genre. This version is the Sega 32X port released in November 1994 as a launch title for the platform, personally spearheaded by id Software's John Carmack.

Players step into the boots of a space marine. While conducting teleportation experiments on Mars' moons, Phobos and Deimos, the Union Aerospace Corporation (UAC) inadvertently opened a gateway to Hell. With the base personnel either slaughtered or transformed into the undead, you must fight your way out alone.

Game Features

• Classic Run-and-Gun Exploration: Navigate labyrinthine levels to locate red, blue, and yellow keycards to unlock corresponding doors, with secret areas concealed behind suspicious walls throughout.
• 17 Levels Included: Features maps adapted from the first two episodes of the original PC release: Episode 1 ("Knee-Deep in the Dead") and Episode 2 ("The Shores of Hell").
• Iconic Bestiary: Battle Zombiemen, Shotgun Guys, Imps, Demons (Pinkies), Lost Souls, Cacodemons, Barons of Hell, and more.
• Arsenal of Weapons: Upgrade your firepower from fists, a chainsaw, and a pistol all the way to the shotgun, chaingun, and rocket launcher.

Differences from the PC Original

• Lacks Episode 3 ("Inferno"), as well as three enemy types: the Cyberdemon, the Spider Mastermind, and the Spectre.
• The BFG9000 cannot be obtained during standard gameplay.
• Monster infighting is disabled; baiting enemies into fighting each other does not work in this version.
• The gameplay viewport is bordered rather than full-screen, running at a lower resolution than the PC version.
• Single-player only—multiplayer deathmatch and co-op modes are not supported.
• The game lacks a native save feature; you can only use the level select to begin from any of the first 15 levels. However, our browser emulator supports save states, allowing you to save your progress at any time.

How to Play on PC

1. Click Start Game and wait for the game to finish loading.
2. On the title screen, press Enter (mapped to the controller's START button) to open the main menu, then choose your game and difficulty.
3. The mapping between your keyboard and the Sega controller is shown in the table below. Key bindings for fire, open/use, and run can be viewed and remapped in the game's Options menu.

Strategy & Tips

• Hunt for Keycards First: If you get stuck, chances are you are missing a keycard. Check your automap to spot colored doors and determine which key you need.
• Interact with Suspicious Walls: Walls with misaligned textures, seams, or flickering lights frequently hide secret areas stocked with armor, ammo, or heavy weapons.
• The Shotgun is Your Workhorse: Extremely reliable and ammo-efficient for dealing with Imps and Shotgun Guys at close-to-medium range.
• Never Fire Rockets at Close Range: The explosive splash damage will severely injure or kill you.
• Use Explosive Barrels: When enemies cluster around toxic/explosive barrels, shoot the barrel to wipe out the whole group in a single blast.
• Make the Most of Berserk Packs: Picking up a Berserk pack dramatically boosts your melee damage, allowing you to punch Demons to death in a single hit.
• Strafing Works Differently: The 32X version lacks dedicated strafe keys; you must hold a "strafe modifier" button while pressing Left or Right. Consequently, fluid circle-strafing like in the PC version is much harder to pull off.
• True Ending Requirement: You must play through from Level 1 to Level 15 in one continuous run without using cheat codes or level select; otherwise, beating the game will simply dump you to a mock DOS prompt displaying C:\DOOM>.
