Alienswarm 2! Woohoo!
Remember Alienswarm? I just read on RPS that its successor is coming out on monday. On Steam. For free. Bloody awesome! Turns out the creators of that awesome UT2k4 mod where bought up by Valve a while ago, took part in L4D and Portal2 development and now got to realize there Alienswarm successor. I'm so looking forward to monday now, demod and me will most certainly spend a lot of time on this, best co-op game ever.
There's also another trailer available on the Steam page.
