I know the information page for Alien Swarm does not list it, but from the screenshots it seems like a perfect game to control with the xbox controller.
Did they just forget to add the icon or is it really not possible to use?
I guess I'm asking this question to somebody who has played the game

It does require you to go into the console and enable the xbox controller. I've got it working fine on my game, I just need to figure out how to customize it because currently it is not allowing me to swap weapons via controller.
As of 2015, go
exec 360controller_xbox
(or tryexec 360controller_pc
