Steam2 leak Alien Swarm

[PrisenShift]

Were there any early builds of Alien Swarm in the Steam2 leak? I’m not exactly a fan of the game, but I’m curious nonetheless. The leak contained literally all early versions of Valve multiplayer games developed between 2008 and 2011, yet there’s no mention of Alien Swarm, even though, based on its development timeline, it should have been there.
