I tried out savegame 4 Marduk head, and when I try to leave the room the elevator (behind the door that is now open) won't move, there are no buttons to press (and the holes in the floor where I came through are closed).
So I'm trapped!!!
I'm either doing something wrong or this is as far as I will ever get on this level.
Thanks again for all the savegames, don't worry about making any new ones, I'll wait patiently for Emperor's Tomb.
