If you find yourself in the unfortunate situation of being a gamer that hasn't played "Left 4 Dead" yet, you probably should take care of that. Luckily, Valve will be putting it up on Steam for FREE this Friday. Yes, there's a catch, but it's still pretty cool:
Yes, instead of spending $40 on the game, you can spend $0. The catch? The offer's only good for a 24-hour period, and once that 24 hours is up, the "free" game will be locked, and you'll need to pay up to play up.
