It’ll go live on Steam from the mod’s developers, Black Cat Games, who are now Valve employees. It’s a top-down co-op shooter with aliens!
”Available free of charge, the game thrusts players into an epic bug hunt featuring a unique blend of co-op play and squad-level tactics. With your friends, form a squad of four distinct IAF Marine classes,” blurbs theSteam store page for Alien Swarm.
”Plan your attack using an unlockable arsenal of weapons with countless loadout configurations against a wide variety of aliens. Blaze your way through an overrun, off-world colony, eradicating the alien infestation in environments ranging from the icy planet’s surface, to a subterranean lava-flooded mining facility.” Not bad for free, eh?
It also comes with the ”complete code base” so modders can tinker with this mod-based game, built by modders modding another game… mods! We love ‘em. Steam also chucks in 64 achievements for good measure. Is it free forever? Maybe. Wanna risk it?
