Id Software’s follow-up to their genre-defining Wolfenstein 3D, DOOM is another first-person 3D shooter: full-on action seen from the space marine’s perspective. It falls to the surviving marine to grab some guns and strike back at the demons. A squad of marines is sent to Phobos, but all except one are quickly slaughtered. Phobos base is overrun with demonic creatures, and the whole of Deimos simply vanishes. It seems the scientists have opened a gateway straight to Hell. After early successes, something goes wrong. The Union Aerospace Corporation has been experimenting with teleportation technology on Mars’ moons Phobos and Deimos. Play Doom online here!
