Short and to the point. If you want to get your hands on the best co-op game currently available, and don't have Left 4 Dead yet on the PC - now's your chance. Valve is offering the game for 50% off this weekend only. That means the game is only going to set you back $24.99!
So hurry up and snag this great game if you haven't already, we know it's good - and you should too. While you are at it, why not join our Steam group?
