the one where you have to play with 3 ppl not on your friendlist.
wee can just delete each other, get together on one level, finish it and add each other again?

I'm not sure if this would work (it worked for the 3 players on your friend list trophy) that someone uses 2-3 controllers finish the level that way.
obviously it wouldn't work for that one person. but hey, if it works, i have 3 controllers too.

tried for 3 days straight now, no luck.

i need it too. if you see me online when i get home in three hours, send a msg on psn
