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 :)
Doom was action and Doom 3 try to be a horror game. But it does not work as everything is so predictable that one almost fall asleep. Every monsters stands where you think it will and the only horror is when you walk to the next level and see that it is the same sci-fi labs environment as the last one. There are max three monsters at once and the first time you meet a new monster they break the flow with a worthless cut-scene to show it off. Doom I and II are great games and Doom 3 does not deserve to use the same name.
This is a basic Doom 3 expansion without any real value. All bad things on Doom 3 still apply and they also added a new weapon that works the same as the Gravity Gun in half life 2. There is not much use for it as so few things in Doom 3 can be interacted with.
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 .
