Dos game search

I have been looking for a game from the 90s for YEARS and thought id reach out here. It was a top view game where you went around shooting people then You had to find the exit. It was a 1 player or 2 player game but on the single keyboard with a split screen. Very vague description sorry. I used to play it with my brother. He reckons it was called wardogs but no matches.

Pretty sure we got the game on a demo cd that came with aninternet magazine. Any suggestions is appreciated
