Could someone link me to a guide on how to set up coop maps? I was playing as blue, entered "map mp_coop_they_still_apply" for the map "the laws of physics, they still apply" and the game booted both my partner and me. For me, it had opinons to return to the game or hub room, but they didn't work. Not sure what my partner had.

Do we both have to install the map? There was also other files in the download, but the readme said to only use the .bsp file.

I can get singleplayer maps to work just fine.
