In July of 2010, Valve released Alien Swarm, a free-to-play, top-down co-operative action game. Previously known as “Alien Swarm: Infested“, it had been in development since 2005 (and was meant to be a follow-up to the original Alien Swarm, for Unreal Tournament 2004).
While it was an undeniably solid game, for Valve it might have represented an experiment in how modding works: “If we give the modders a free game and free tools, but offer little support, will they keep the game alive?”.
It was an interesting question, and one they have hopefully found an answer for. Make no mistake – Alien Swarm‘s community may be tiny, but it is extremely active. And what better proof of this than the mod I am about to show you?
