Mother of all First person shooters (ok, wolfenstien was first but it was boring). In this game you are stuck on one of the moons on Mars guarding the geeks that work there and then a experiment goes wrong (like they always do) and the portal to hell opens up and demons attack and rip your friends apart. You need to slay the hordes of hell and stop them. Fun both in single and multiplayer, co-operative rules . Coolest weapon must have been the plasma gun and the chainsaw, I like the idea that they had any use of a chainsaw in space :)
Here I write what I think about the games I have played. The score is shown as a smiley before the title of the game.
Note about Movies: None of the Youtube movies that i link to are made by me and i include them only to give you a chance to see what the game looks like. Only the text and the smiley score act as my review of the game .
