I was playing the Xbox 360 version of Crysis 2 campaign on Veteran and had some issues pop up.

Issues:
1. Enemies (Cell) floating in the air after killing them.
2. Enemies (Cell) fall through the floor after killing them.
3. Enemies (Alien) continuously running into objects.

Other:
1. When on "Lab Rat" on the other end of the pier there is a rock that's missing a side.
