Can Portal 2 be played with friends cross-platform?
I bought Portal 2 for PS3 and one of my main beefs is that you can not play online Co-op with people unless they are already on your friend list. Since that limits my pool of online partner candidates to ZERO (waahh I'm such a loser), I can't a) play co-op unless my real life friends come over and play split screen or b) get all of the trophies. One of my friends has it on PC though and I was able to add him to my list of Steam friends but I haven't tried to see if I can play co-op online with him on PC and me on PS3. Does anyone know if this is possible?
Since there is no online matchmaking with random people who want to play co-op, I'll never be able to play online unless someone on my friends list has the game already. Sorry if this question is confusing!
