Currently myself and a few good men are revamping some existing models I had in THC3 and adding in new ones. I don't want to release too much so 2 screenshots will have to do.
The Mercenary's weapon of choice. Automatic, zoom capable, rifle that shreds flesh and armor alike with 30 rounds per clip
Meathook revamped, this one is pretty pointy and does a great job taking out zombies one by one. Unfortunately when multiple zombies enter the picture sometimes It just can't dish it out in time. Of course this weapon more than makes up with it for it's primary attack is an over the shoulder whip down onto your enemies at relatively quick speed. But the killer attack is the secondary swing capable of decapitating your victim or cutting them in half completly.
