You can unlock the upcoming Left 4 Dead 2 DLC title “Dead Air” early, if you’ll so kindly hop on Steam and complete the recently released community created map, “Cold Stream”. Â Valve announced the promotion just a short while ago, and it will only take 20,000 players to unlock the achievement in the game to release the content for all on July 22nd. Â The achievement you’ll be shooting for is Stream Crosser, which will unlock if you finish the campaign on any difficulty.
The Left 4 Dead 2 community is still going strong of course, so this probably shouldn’t be a problem, but the more help the better. Â So hop on, and help us out. Â If you don’t have Left 4 Dead 2 on PC, you’ll be glad to know that you can pick up what is probably one of the best games of this generation for less than a value meal, at a paltry $4.99.
And this is why mod tools are important. Â Two years later and the game is still being played by a robust community, with a wealth of free downloadable content to add even more value to a game that costs less than five bucks.
