Gears of War
Big bald soldiers with big guns that fight against evil monsters and a really stupid story. Nice and fun as long as you play co-op and remember to press skip as soon as a cut-scene is about to start. One thing that stand out is the focus on cover in the game and all battles is based around moving from cover to cover while shooting the bad people. Works nice.

Did I mentioned that the story is really stupid?


Gears of War 2
More stupid story, more big guns, more aliens that need to die, less hair and more one liners. Do not think... press fire. Still cover based battles and it still works well even if it looks strange that the whole world if filled with waist high concrete blocks. Co-op still great.


Gears of war 3
Last part of the Gears of War series and I think they have a real writer now but it's to late as I do not care. Each cutscene is painful as always. Mechs was fun to use.


Halo 2
Second part in the halo series and this time your time is split between playing two characters with to simultaneous story lines. The first one follows Master chief and the second one follows the Arbiter who is the alien who failed to defend the Halo against the Master chief and friends in the first game. The campaign can be played with two players in split screen and the game also had a nice double-wield support where you could mix weapons.


Halo 3
Final game in the Master chief halo series for now. The Arbiter and friends has joined up with humanity to fight The Covenant and you once again take to role of Master Chief to save the day. Played this one in co-op to and don't really remember much from the story other than the fact that each new area you enter is so filled with epic music and dramatic cut-scenes that you almost puke. In co-op one player takes the role of the Chief, the second one the Arbiter and the two last players will play as aliens of the same race as the Arbiter and it all work out great with all the cut-scenes fixed for it to.


Trials Evolution
Racing game where you use a motorcycle to traverse an obstacle course. Looks 3D but the gameplay is in 2D. Four players is nice on the same screen.


Trials Fusion
More trails madness.
