Ok just back from a 2 hour coop session. In one word: WOW
It's been a long time since I've had that much fun on Live. Playing this with a good friend is of course a big help

Anyway, a few OMGWTF moments from the first coop level :
- Entering a room with 2 guys watching a soccer game, so they do not pay attention to the rest. Me and my friend pull our guns out, count to 3, fire. Both dead at the same time, one bullet in the head. Hitman style.
- My friend hanging from about 5 meters high, and me in another part of the room, waiting for a guard to walk right under him waiting for me to tell him when to jump so he can time the fall right. Bingo, guard dead after trying to catch a full grown man with his head.
- Me hanging upside down from the ceiling by a cord, with my friend 10 meters up controlling my movements. Type in the code, open the big door, alerting all guards. I start frantically shouting to him so he get me up, and it's going soooo slowly, I can see all guards converging on my position but having no idea I'm on top of them. Big adrenalin shot there

- My friend doing noise to attract a guard right next to a door, and me using the bash door command to knock the guard out.
It took us about 2 hours to complete the mission (we both suck). Only downside is that we got 2 disconnections (don't know if it's the game or our ISP acting up) and some severe slowdowns in 2 areas.
What a blast this was. We'll make a video of the best moments of this level tomorrow
