Counter-Strike: Source
Multi player only game with two teams, the terrorists and the counter-terrorists. At the start of each round all members of a team spawn in their buy zone were they can use the money they have to buy weapons. You gain money by killing the enemy and completing the goals of your team.


Day of Defeat: Source
Class based first-person shooter set in World War II.


Half-Life
In Half-life you play Gordon Freeman, a new employ at the Black Mesa research facility. Like always the experiment goes wrong and portal is open to another world and monsters attack. Our hero picks up some guns and the game turn into a very nice first person shooter. Overall a great game but with some sections a bit to long. The end is also long and boring.


Half-Life 2
Gordon Freeman is back and now the aliens have invaded earth. The game takes place in and around City 17, a city controlled by the invading forces and besides running and shooting you also get the chance to drive a boat and a car. The game has the same problem as Half-Life with areas were they run the same idea for to long and it grows tiresome. The story is also bad, it feels like a movie with some good action scenes that don t really fit together that well.


Half-Life 2: Episode One
First chapter in the episodic releases of the follow-up to Half-Life 2 where you as Gordon Freeman and your sidekick Alyx try to escape the City 17 before the Citadel reactor explodes.


Half-Life 2: Episode Two
Second episode from Half-Life 2 and this time you are outside the city trying to get to a resistance base called White Forest. You get a car in this episode and spends a lot more time in open terrain driving around.


Left 4 Dead
Great first-person shooter co-op game where you and three others try to survive a zombie apocalypse. Each chapter in the campaign mode is about getting to the escape vehicle and characters not played by humans will be controlled by the computer until someone joins to play with you. You fight your way from one safe room to the next and if you all die you restart at the last one. The zombies in the game are slow to notice you but when they do they really moves fast and there are also a number of special zombies that demand special tactics. All in all a great game that is really fun to play and it's nice with a game to proves to idiots that people indeed play coop games (you know who you are...).


Left 4 Dead 2
Four new survivors need to survive the zombie onslaught and this time it is possible to use melee weapons to kill of the undead. Chainsaw is a favorite like always in every zombie zombie apocalypse :).


Portal
Puzzle platform game that only real shortcoming is that it's to short :). In it the character you play is stuck in a laboratory and subjected to experiment by a AI named GlaDOS. You are forced to use a portal gun that creates space portals between flat surfaces to solve puzzles by GlaDOS while you are looking for a way to escape the laboratory. The sad part is that when you finally get a hang of the portal gun the game end's so it feels like playing only the tutorial part of a full game :(.


Portal 2
Time for more portal puzzles and now also with tractor beams, light bridges and gels that give surface special properties such as jumping higher. GlaDOS is back and also new characters like the robot Wheatley that help you and Cave Johnson, the deceased CEO of Aperture Science. Great voice work with funny dialogue on all characters in the game.


Team Fortress 2
Team based first person shooter where cartoon styled red and blue team shoot it out. Nine player classes to pick from and wherever you pick there is always a spy with a knife with your name on it waiting in the shadows.


The Lab
VR technology showcase set in the Valve Portal universe. Shot a bow, play with a dog and move on to another game.
