Insane action, fast movement, and very simple.

RPG and FPS in one.

It's like half-life 1, except it's better, it's got a different arsenal of weapons, and a much more open world to explore. Also you conquer robots.

This game is an even further extension of the half-life story. Its such interesting and ou should get it right now.

Same as half life, except more story, more weapons, and a whole new race of aliens!

A rather interesting game. Also you should definantly get it.

A simple horror game that is overwhelmingly great.

Its like Tf2 and CoD had a baby!

If you like the most open sandbox game you can find, and with no limits (you can play until you crash), then THIS is the game you will NOT regret.

The only game in the world where you can were non-armor accesories and hats, trade with other players, and do high fives during an intense fire-fight.
