AT-ST's are able to shoot behind themselves.

In the original JK, the AT-STs needed to turn around before they could shoot you. In OpenJKDF2, they can just shoot backwards.

This is an issue in the original JK, AT-STs can and do shoot directly behind themselves if they are aware of the player. Tested and confirmed as I was only 90% sure.

AT-STs have weird issues as well, such as collision being off with lightsaber hits on the legs usually strike an invisible hitbox. Meanwhile, hits on visible areas of the model do not register for collision/the hits. I don't know how much OpenJKDF2 will fix these AT-ST issues, but they are the buggiest enemy in the game by a mile.
