Best version of Corpse Killer, that's for sure. Outdoes the Sega CD and 32X by a long shot, and offers much faster gameplay that's more challenging, and entirely full screen video that's much clearer. What's better, the controls have been overhauled and improved on from the Sega CD/32X versions. In the old versions, you had to keep pressing B to get to a certain weapon. The saturn version has a specific function for each of the 6 buttons on the Saturn controller and lines them up so it's easy to use.
AS far as FMV games go, there are worse ones than Corpse Killer. But it's an inventive and hilarious B-movie style FMV game that really makes you laugh and is a joy to play. It's basically a cross-hair moving shooter that is more ideal to play with a light gun of some kind. But it's easy to pick up and play. Great game as long as you don't pay too much for it.
