I picked up the 4 pack for Pay Day 2 "cheap" on steam.
I watched some of the preview videos a few months back and I was less than impressed - it just felt too violent for violence sake, but given the week I've had at work it seemed less of an issue with me and I pulled the trigger (get it?).
Who wants a key (and will actually suit up and try to give multiplayer a shot)?
UPDATE: Rudy's in! 1 down, 2 to go...
