Sweet! I remember quite a few of these from my local hometown video store before it went out of business. Mutant Hunt especially. For some reason I never thought to rent these gems, but I always remember the cover art.
Edit: Oh MAN! This one I've been looking for!!
This is easily one of the worst movies I've ever fucking seen. The beginning intro and theme music is so fucked up (it must have been stolen from a bad '80s 'Care Bears' styled cartoon!) that you can't help but laugh at it.
