In a CES trailer showing off the some of the weapons physics, we get our first glimpse of Killzone 2's Arc weapon lightning gun and a new enemy type as well.  If it weren't such a bloody mess, it would make a pretty amazing commercial, no?

Killzone 2 is a first person shooter developed by Guerilla Games.  The title is due out February 27, and is exclusive to the PS3.

The trailer can be seen here, courtesy GameTrailers.
