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. 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.

Rather than an update to the Source SDK itself, Alien Swarm will receive an SDK of its own. This allows Valve to make it freely available to the whole world (as opposed to existing owners of Source games) without also granting access to HL2-mounting Source 2006/2007 mods - a mirror of the [http://www.udk.com/ Unreal Development Kit], which includes only a subset of Unreal Tournament 3's content. There is nothing confirmed either way yet.
The SDK is available to ''everyone'', not just owners of Source games.

Alien Swarm Alien Swarm (2010) is a completely free top-down shoot-em-up for up to four co-op players, which is a remake of the Unreal Tournament 2004 mod with the same name, created by Black Cat Games after the company was bought up by Valve. Its complete source code is provided in a new SDK as a sample project for Source modders, much like Ricochet Ricochet and Deathmatch Classic Deathmatch Classic were for GoldSrc GoldSrc.

A mod based on Alien Swarm will not require the purchase of another Valve game to play, but it will not have access to the usual "Source base" HL2 content either.

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. 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.
