User Rating: 10 | DOOM PC
For those of you who have never played DOOM, you start off on a base on one of mars' moons. You enter one of the facility's on mars' moon to discover that the whole base is overrun with demons,and all of your friends are dead or possessed/zombified. You eventually make it to the place where the demons originated(****). There, you go through jungles and mazes solving puzzles which involve finding keys, locating hidden switches, and stepping over invisible lines which can cause changes in the environment, all the while killing hordes of demons and the undead and listening to the pixelated heavy metal music in the background. Also in doom is the famous BFG(Big-F'n-Gun) which can slaughter whole rooms of enemies at once. And you'll never run out of levels. There are thousands of custom levels available for download, and DOOM level editors are shareware. Everyone should have this game.
