I might be playing through Resident Evil 5 in co-op. That is, assuming my friend managed to get his hands on the game. He made me promise not to play too far ahead on my own beforehand. But that didn't work. Don't tell him though.
If he doesn't get the game in time, I'll probably scratch that zombie-shooting itch in House of the Dead: Overkill, trying to unlock those last few, er... unlockables.
So how about you? What games will be occupying your time this weekend?
