Valve is continuing is grand tradition of releasing quality content for free by giving away the Survival Pack, an expansion of everybody’s favorite zombie shooter, Left 4 Dead. This in addition to the upcoming Scout Pack for Team Fortress 2, again for free. This is how it should be done, people, although I’m not sure how Valve can afford it.
The Survival Pack will have two new campaigns for Versus mode and a new “Survival” mode, which sounds sweet. I’m guessing it’s a slowly increasing zombie horde in a set defensible position like the setpieces at the end of every campaign. So awesome.
