Although that’s not stopped other companies trying to charge for previously free content in the past.Alien Swarm is a top down shooter heavily influenced by Alien Syndrome, Alien Breed and other games with Alien in the name that are also trying to rip off the eponymous movie series. This will allow them access to the game’s code and let anyone customise and change the game however they want.The other main reason that it’s free is because it’s a remake of an Unreal Tournament 2004 mod of the same name. Valve’s interest in the game appears to be as a testbed for releasing a full software development kit (SDK) to fans, without requiring them to make any prior purchase. Games like Pop Island on the DS may be incredibly cheap, but this new game from Valve goes one step further: it’s completely free.If you click along to the Steam website you can download the whole thing for nothing, and all without a smear on your conscience. The summer may not be a good time for new game releases, but it is apparently the season of unusual generosity and goodwill for publishers. Alien Swarm (PC) – they’re coming through the goddamn walls, etc.
