Spent 40 minutes trying to play online earlier. Every game was a massive lag filled fest. I ended up giving up. It's a massive clusterfuck atm (360 version).
I think I have managed to only get like 3 lag free games since launch.
Ubisoft need to step their game up and fix this asap.
Edit: I am liking the SP aspect, but am disappointed over the changes made. Why ditch the design from E3 2010. I loved that design/setting. The game was darker, and the futuristic designs/elements were really good imo.
I liked how aiming switched to first person view.
Hopefully that version makes a return
