1) how do you play portal 2 co op without partner connected aka, how do u initiate a co op game without a partner (i know this is possible since i've already seen/heard several ppl do this, they complete the levels at the end using noclip i believe). I can "map somecoopmap" ... but it exits with "partner disconnected"
2)when trying to load a custom map, whenever I use "map somecoopmap" it disconnects partner but when I use "changelevel somecoopmap" it says :
"Can't changelevel, not running server"
3) i was playing co op with some random, this person set sv_cheats to 1 .... i couldnt set it back to 0, what gives? ... it's a coop game ... shouldnt both partners have a say in this? hehe
4) when sv_cheats is enabled there's several things you can do, like placing portals everywhere, shooting stuff (lol), shooting bobbles of gels ... how to i do these things?

Happy Testing.
