I spent some time last week playing through two maps and two modes of multiplayer in Crysis 2 during GamesCom, here's a closer look at those levels.
The art here includes the tactical maps for the maps Impact and Rooftop Garden. There's also a look at the pod that drops during the multiplayer mode Crash Site.
In Crash Site you are competing for control of Ceph Drop Pods launched periodically into the map by orbiting dropships. The mode isn't really new, with one exception: Those drop pods can kill you if they land close enough.
The game's Team Instant Action is team death match, just trying to get the most kills and least deaths in a match.
