Just ran this for a couple of friends - GREAT FUN!
Epic boss battle at the end: missed with the rocket launcher, only one hit with the Magnum, came down to their last shotgun shell as the BBEG closed to melee range and was about to bite their heads off - absolutely awesome grand finale for a blockbuster horror movie!
Highly recommend giving this a go when you want a one-shot to fill the gap between more serious/on-going games.
