Thank you for releasing the installer for the new version. I am sorry but it seems my first post wasn't as clear as i intended it to be.
The Telic Campaign is an unofficial expansion pack for Alien Swarm that brings eight new, unique missions in the form of a complete campaign. In addition to the maps, Telic expands the Alien Swarm universe with new weapons, extra items, more dangerous enemies, original mission objectives and various modifications to the standard game rules.
These expansion pack has a unique website and an own "installer". Both (AS 1.3 and Telic) were released the same day.
The url is:

Maybe you can catch the zip and create an installer
