Hey guys, just found how to practice co-op maps in single player. Start any single player map, then just use the changelevel command to a multiplayer map. You have to use the give\_portalgun and upgrade\_portalgun command, but I figure it’s worth it for practicing routes on your own 😃

yeah, you’re right, but i seem to have a problem with the command to change maps. when i start one, the game goes in pause mode and i can’t continue the new OR the old map…
