Left 4 Dead 50% off weekend
In order to celebrate the new Crash Course DLC, Valve is offering a 50% discount on Left 4 Dead this weekend, meaning the game will cost a meager $15. To make the deal even sweeter, the new offer includes the recently released DLC as well.
However, considering that Left 4 Dead 2 will be coming out in about a month, some might be tempted to wait and get the sequel instead, which we can certainly understand. For everyone else though, $15 sure buys a lot of zombie slaying.
