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.


Unreal
First-person shooter where a prison ship with the player as a prisoner crash on a alien planet called Na Pali and the player need to escape from it. You fight the evil Skaarj that now rule the planet and get some help from the Nali, the former rulers. Nice levels to explore but it feels wasted on a first-person shooter.


Unreal Tournament
First-person shooter that focus on competitive playing against other players. Has the basic game modes such as deathmatch and capture the flag, the one that stand out is Assault. In it one team is set to attack and the other to defend and what needs to be done depends on the level. Unreal Tournament also has weapons with both primary and secondary fire and most are forms of weapons from Unreal. Some game modes also had the Translocator as a weapon, a form of personal teleporter that the player could throw out and transport to.


Unreal Tournament 2003
The second version of the Unreal Tournament series. Not that much new that makes it worth playing but the new game mode Bombing run where you need to shoot a ball in the other teams goal was fun.


Unreal Tournament 2004
Second follow-up on Unreal Tournament. The new game mode Onslaught was great fun where you could also use vehicles and the goal was to destroy the other teams reactors. Played this so much I was dreaming about flying around that tower on the demo level :).


Unreal Tournament III
To much Gears of War graphical style in this for my taste and they also added a horrible single player story. Warfare is the new name of the Onslaught from Unreal Tournament 2004. Now most game modes have a option to play with vehicles.


Unreal: Return to Na Pali
Expansion to unreal were we get to learn what happened to our hero after the events in unreal. Not that epic really :(.
