I was surprised looking at the HOL entries for Cadaver that two of the demos are missing. These two demos are more like mini games just like
Cadaver: The Last Supper which is listed. A researched the Cadaver games a while back and so for the record here is more info on the these mini games:
Cadaver: Gatehouse:
This is the earliest of the three Cadaver demos with the controls that are slightly different from the full game and the oher demos. In the demo you must find your way out of the 'Gate House' so you can venture to Castle Wulf where the full game carries on the adventure.
Appeared on Amiga Format issue 13 (August 1990)
Cadaver: Temple:
This is Considered the hardest of all the Cadaver demos. Unlike the other demos it doesent logically precede or follow the adventures of Karadoc in the full game or its data disk The Pay Off.
Appeared on the magazine Zero issue 16 (Febuary 1991)
Cadaver: The Last Supper:
The demo was not actually done by The Bitmap Brothers but by a group called Soldiers of Hell (HOL entry is wrong), they are an officially sanctioned set of unique levels. The story takes place in 'Zeigenhoff' straight after the adventures of The Pay Off.
Appeared on the magazine Zero issue 23 (September 1991)
Please feel free to use this info on HOL in any form you wish.
