Ahh, Halloween! When people think of this holiday, they tend to think about costume parties, mountains of candy, and the living dead overtaking the world. Truly it is a wonderful time of year.
With that being said, Valve is going to help you celebrate Halloween in style this weekend! That’s because Valve will be making Left 4 Dead 2 free all weekend on Steam, until Monday at 10 AM PDT. That should give you plenty of time to kill off as many zombies as want.
Those of you who already own the game will be getting a perk as well! If you already have the game and you help one of the free weekend players survive a campaign you’ll get the Good Guy Nick achievement. So what are you waiting for? Go pick up that shotgun and Molotov and get to killing!
