Thanks Swine, but I checked out Descent, and it’s not No. 2. I said they were obscure!

In the game, the player was very ground based at first. An interesting element of the game was, if you ran out of batteries/charge, you would collapse, unable to complete the level. The very first gun was a pistol of some description.

mterek, was your game Nitemare 3D? There are robots, something that looks like a giant rat, and you fight a Doctor (although his name was Hamerstein) in order to rescue your girlfriend.

EDIT: I found No 1! It’s a game called Necrodome! Unfortunately, the reviews suggest that it isn’t that good. Still, it’s nice to have found it again!

EDIT THE SECOND:I found No 2, as well. It’s called Rex Blade Domination, and according to Gamespot it was crap. Interestingly, it had a built in programming language which allowed you to do… stuff… within the game. How this helped you shoot things I don’t know, but I was only 10 or so when I played it.

EDIT THREE: THE SON OF EDIT: Actually mterek, I think your game may be The Fortress of Dr Radaki, as the box-art has a pretty prominent robo-brain. Here’s some gameplay:

I think there’s a torrent with the game in it avalible at the FPS archive.
