Anyone who’s played Left 4 Dead 2 at any point in the past year has had access to a beta version of Cold Stream, which was announced a long time ago. Most people might have forgotten that it’s still in beta, and thought Valve might be done with it. However, that’s no longer the case as it’s receiving the full DLC treatment and is being released along-side some other fun things on July 24th.
So, what’s coming with Cold Stream? Well, they’re taking out the weekly cycle of Mutations and just making all of them available. This is a first as well, and will be the best chance to play any kind of mutation whenever you want.
Cold Stream was a good map whilst it was in beta, and soon that won’t be the case. So since we’ve had the map for so long, hopefully Valve will put a little spin on it to change it.
