So I've decided to use the Alien Swarm SDK and get started on mapping for Portal 2. I really want to focus on coop maps, however I am already stuck... I can't seem to get the players to move at all? If I do ss_map mp_coop_lobby_2, it works, and I can move both characters. However, when I load the test map that came with the portal 2 FGD, I can't move either character. I also tried making a very basic coop map with just 2 spawner's in a room, one for blue one for orange. I used the info_coop_spawn for both players. Just wondering if there is something I am missing, I have searched for a while but can't seem to find any answers.

I haven't had a chance to test with a partner yet, it may work that way, but its not in split screen, maybe I need an extra entity for split screen?

Any help is appreciated, thanks.
