OK, srsly, I'm enjoying this game immensely, but don't think I can play through ALL the story missions a second time just to get the "Partners in Crime" Achievement (all missions in co-op, 100G). If I can get a co-op partner for the first mission, the jailbreak, I can probably mop up the rest over time. That first mission, though, apparently requires that you have a co-op partner from the get-go, where others allow for replay.
Or does anybody know if they patched it so it finally works on regular re-play through the University crib?
