I am keen to play steam games as well have added a few of you to my steam account and had a look at what games you have, now for multiplayer games we have a few to pick from the list goes- Serious Sam 1 to 3, Team Fortress 2, Modern Warfare 2, Counter Strike, Black Ops, Bad Company 2, Battlefield 2, Hot Pursuit and Alien vs Predator.
Co-Op we have- Pay Day, Left 4 Dead 1 & 2, Borderlands 1 & 2 and Dead Island.
Plenty to pick from and with Xmas coming up there will be big sales on steam if you want to get some of those games.
