For people and teams developing mods and games with Valve's Source engine.

Report content RSS feed Valve announce Alien Swarm

A new TFC! Black Cat Games were hired by Valve two years ago and have been quietly developing AS for Monday's free release, which includes source code.

Posted by Varsity on Jul 16th, 2010

Valve say:

Alien Swarm is a game and Source SDK release from a group of talented designers at Valve who were hired from the Mod community.

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. 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.

Along with the game get the complete code base for Alien Swarm that features updates to the Source engine as well as the SDK. Alien Swarm adds 3rd person camera, depth of field, improved dynamic shadows and a wide variety of gameplay additions to the Source engine.

There will NOT be Mac support, or source code, on release.

I'd guess you won't get the 2004-version of HL2, you will either get the today's version, or even a more evolved one.

Loved the UT2K4 mod, can't wait for this.

Is it a free game that allows anyone to use the Source SDK, or is it a free game released by valve that requires you to have the Source SDK?

It's not a silly question. AS gives you the SDK according to the store page, so *if* it's free to everyone in the world then Valve are making all Source mods free to everyone in the world as well.

They'd be making some noise if that was the case, so I expect it will in fact only be available if you own the SDK already.

Well, source mods are already free for everyone, just grab HL2: DM at one of those steam offers by NVIDIA or ATI.

They are just gonna give it for lazy people.

Nope, those deals don't give you the SDK.

Maybe, we're getting some kind of "limited" SDK like L4D2 SDK.
So you could only play mods for L4D2 and make maps only for L4D2.
Same here. Limited AS SDK. You could only mod and map for AS.

That now seems to be the case. The AS SDK will be separate from the Source SDK.

SteveUK Jul 17 2010 replied:

The mapping part might be separate but I don't think the code is, it's already been said it brings the >Source SDK< up to the latest Source version.

Medevila Jul 18 2010 replied:

The way SteveUK put it- that's is how it is. The mapping is separate because of the nature of the game, but you still get good ol' Source SDK though.

The official announcement is that you get an Alien Swarm SDK, not source SDK and even if you did get source SDK it would not let you use mods because you don't need source SDK to run mods you need "Source SDK Base"

Holy crap! I played the UT2K4 version of this! Awesome! Awesomely awesome!

I wonder if mods will be able to move onto the updated engine (ie unlike the L4D2 engine updates). And the game itself is fully moddable? Epic.

Announcing L4D2 was perhaps little bit harsh move, but now this? Valve know how to keep players interested. :P

Shadowground is also good game and this one looks bit similar. Unfortunately Shadowgrounds never provied multiplayer support, so thats why I'm so excited.

subenji99 Jul 16 2010 replied:

This is incorrect: there is no mention of Mac support on either or

A chatlog was posted on several places allegedly showing a comment from a Valve employee that the title will not be a simu-release; that honour is still reserved for Portal 2 - but that "maybe" a Mac version will be forthcoming.

// the chatlog in question:
2:45 PM - HaekB [reddit]: wait alienswarm isn't coming to mav?
2:45 PM - HaekB [reddit]: mac*
2:45 PM - ~TGG~ BurdenJ: Nope
2:45 PM - ~TGG~ BurdenJ: Portal 2 will be the first simul-release
2:46 PM - HaekB [reddit]: ooh, so i assume it'll eventually get mac support?
2:47 PM - ~TGG~ BurdenJ: Maybe

I was willing to assume that would be on Mac, but that chatlog tips the balance. Profile updated.

There's still a good chance the "PC Mod to Mac" Compiler will be released.

But not the same second, minute, day etc.

Alfred Reynolds has already said there's going to be Mac tools, but they aren't ready yet. However, this release only brings the Source SDK up to S2009 - no Mac stuff yet.

coolkid87 Jul 16 2010 replied:

well the information i based this off was off the moddb profile and the fact that future valve games are for both Mac and windows. But now that i look into this further, i can see that there is little evidence to support this.
