arramus I'm mentioning this again because looking back I noticed The Fun Pimps have already done a system very similar to the idea of enemy weak-spots in the form of blowing off limbs and heads as well as the detonator on the demolisher being a separate entity so it can be shot to set him off. However the only severe effect limb destruction has is reducing zombies to crawlers by blowing their legs off. but since TFP have done this all they need to do is expand on this and add at least 1 boss type entity to the vanilla game that mods like this one can expand on. Actually thinking about it I'm hoping that new gasser zombie they recently started showing off can have his green bubbles that look like giant pus pockets be destroyed by shooting them to eradicate his gas cloud, if they at least do that then that should be enough to make different weak-spots on the snufkin's zombies.
