Great Coolem C has physical as well as gun weakness (.78 dmg multiplier...if you even wanna call that "weakness")

The physical weakness kinda helps if you wanna place landmines down when sharing and waiting for a spawn on your side...but i only tried this on a lion (which was fun but kinda pretty much a waste of time) as opposed to a fox who can use this to better advantage.
