Loving the hell out of Trenched but just before starting a multiplayer mission with 4 people I got a hard lock that required I completely turn off the system and start back up. Anyone else had this happen to them?

Also, my s/n is Sammo21 if anyone wants to get some games in.

i got a "disc is unreadable" error

I had one lock up, went to black screen and just hung there. It's an awesome game, but it's still a little buggy, especially in multiplayer.
