So it may not be obvious from this screenshot, but this is not a horror game. Well, not exactly. No, it's a survival sim, and I don't mean the "punching trees" kind. I mean "here's a bunch of pills, syringes, a bone saw, and an in-depth manual on survival, have fun!" kind of survival game. There have been very few games like it since, and even fewer still that let you amputate limbs and survive.
Why is that last point so important? Once, long ago, I attempted a quadruple amputee run of this game. I even decided to start with the arms first to complicate things. While the game mostly adheres to sensible logic, surgery is not one of them, as you can amputate without hands. Life Or Death this is not.
I didn't manage to make it far before a tiger killed me (IIRC, removing your legs prevents you from running, not walking), but I always intended to go back. I even have screenshots of that run I posted to a ZDoom forums thread that is long gone that I may post later.
