There weren’t enough download slots available for the mass of people attempting to download Alien Swarm on Steam, and a number of fans reported slow download speeds when they were able to start the download at all. The original release time was pushed back by two hours, possibly in an effort to prepare the download servers for what was sure to be a massive load once the game was released, however, the Steam servers nearly buckled under the strain. Within a day it was the most played game on Steam, with nearly 60,500 players online during the game’s peak on July 20th. Free Release on SteamĪlien Swarm was released on July 19, 2010, on Valve’s Steam platform as a free download. To stay close to the nature of the mod, Valve planned to release Alien Swarm on Steam for free so that fans of the original and those who had never played it before could both enjoy the new Alien Swarm without having to pay a cent. The game was intended for release as a co-op experience true to the original mod, making it significantly different than the other first-person shooters that had been released on Source. Coming on board to work on popular games such as the Left 4 Dead series, Valve also asked them to begin working on a Source Engine port of their popular mod behind closed doors. Valve’s Alien Swarm began life as a mod for Unreal Tournament, garnering enough attention from the gaming community that Valve extended job offers to the mod’s creators. The game became an overnight sensation, and it’s no wonder when Valve released Alien Swarm on Steam they did so as a free game with a full set of mod tools available for players to expand on as they see fit. This 4-player top down co-op game features frantic action, an immersive environment full of danger, and enough ranks perks and achievements to keep casual and hardcore players alike interested. Capturing much of the feel of the Aliens movie franchise, Valve’s Alien Swarm game puts players in the heart of a space colony that has been overrun by alien monsters.
