This is an amazing real time stratergy game set in the Half Life universe. Play as the Combine or the Rebels, then battle it out, online or offline!

This game is a sequel to Portal, and introducing a new campaign and a co-op mode, it's even better than the first.

Possibly the best puzzle game out there, certainly the best Valve has made. Play as Chell, as she uses portals to complete puzzles and escape.

Another of Valve's amazing games, TF2 has a very good gameplay and new items are plentiful, making it fun for people not wanting to spend any money.

The Orcs Must Die series is back - and with even more ways to kill those ugly, green idiots.

A remake of a great game, Grim Fandango Rematered puts us in the shoes of Manuel Calevera, an undead man on a quest to right his wrongs.

A steep price, although most definately worth it if you like turn-based stratergy games. Countless hours can be had watching enemy cities burn.

Certainly the best of the Mount & Blade games, this game is once again set in the realm of Calradia, as you make your own story in these dark times.

Argueably Valve's masterpiece, this game is set 20 years after the events of Half Life. Introducing new characters and enviroment, this game is great!

A newer version of the older games, this game is still in development, but it has many battlefield-like features and best of all, it's free!
