Good I gave you ideas, but I am actually surprised that there are no special damage areas.
I landed around five clean headshots with Officer Bimbo's pistol, and was able to floor one of the possums, while it took her roughly eight from the same gun to knock one down on body shots.
I dunno what is happening there, it is just kinda funny.
On that note, I think you need to reduce the grenade bounce a little. They bounce too much and end up straying too far away from the hoard to do real damage.
Also, when Clothing damage is implimented, would it start from her pants, seeing as that is where they'd start? Kinda have a thing for seeing gals like her with exposed legs...
