Hello folks.
Never posted here, only made an account for this topic specifically.
Some 20-odd years ago I played a demo of a game that I was never able to finish and later on lost in the deep abyss that is my collection of various hard-drives.
All I remember is that this was a dos game, early-to-mid 90's, which resembled an action-adventure type game. I'm not sure if this game had free movement or grid-based movement, but I do know the scheme was a bit like System Shock (e.g. use mouse to aim and interact with the environment, click to move around etc.)
You start off in a near-pitch-black cave, some rather well made rock-wall or brick-wall type textures, with very life-like/photo-realistic sprites. This engine had textured floors and roofings, as well as different elevated sprites, so it must have been mid 90's.
You wake up next to, if I remember correctly, a well and a skeleton and possibly several torches around the room and walls, the cave wasn't just a simple square room but actually had some shape to it. There's a puzzle you need to solve here, or at least an interaction you need to perform which gives you a rifle of some description with about 3-7 shots. Next, a pack of rats attacks the player which he needs to fend off... what happens next, I can't remember. It might even have been the end of the demo.
