I wish i could still find this. i never finished it and would love to give it another chance.
That said, yeah this is kind of a Resident Evil rip-off, but it's a little more aggressive in nature. Think of the difference between movies: Alien vs. Aliens. That's the diff betweeen extermination and RE. Alien had you running in terror, Aliens had you blasting baddies. Extermination gives you a fighting chance that RE purposefully denies you. Sure it's a little dumbed down, but you can't go wrong for the money. If you find a stash of these, lemme know. I been looking for a year now w/ no luck. heheh.
