DOS Games Discussion

My memory of this game is of a man with a yellow hardhat and a blue jumpsuit, who shoots with a gun, and some of the enemies include snakes and bats. At the intro you land at a space station on a planet, possibly the moon possibly mars. I also remember that there were oxygen producing machines, and if you shot them accidentally you died.

This game was either 90s or 00s, DOS.

Long shot, but Rochard? Or maybe that's a remake of what you want?

Nah that's not the one, but thanks for the input!

FOUND IT! Crystal Caves, I remembered the colour scheme wrong :P
