Trying to find a 90s game

From what I can remember, it was a space game. Player would walk through a tunnel and then be attacked by various monsters. To kill them, you would have to shoot them in a red spot on their body. Monsters consisted of a big space worm-looking thing and a spider - if my memory serves me correctly. Please help!!!

When I have to find something, I use this. It's pretty good.

@so_hai: OMGosh, thank you! I found it! It was Creature shock!

@knv1986: Sweet.
