Valve’s added an updated version of the original Left 4 Dead Terminal Map for Dead Air into Left 4 Dead 2, and it is handing out an incentive to test it for bugs and the like. This incentive will come in the form of an achievement called Connecting Fights, which is earned by playing a complete game of Versus in Dead Air. What’s more, once 60,000 people earn the achievement, Valve will unlock the beta version of Blood Harvest on Steam the following weekday. Think of it as the same as with the Dead Air incentive, only instead of the goal being 20,000, Valve has added and extra 40,000 on top of it. Get to work. Thanks, Shack.
