Looking for 90's Duke Nukemish Platformer with Submarine.
 

I can't remember much about this game. Except for the fact that I played it at my Uncles house, it was a side scrolling shooter/platformer similar to Duke Nukem. And it had an hexagonal (I think) submarine.

From what I played it had caves and underwater caves and the graphics weren't that cartooney for the time.

Anyone got any ideas?

like, you were a character which could climb into the submarine? or it was only a submarine?

also, what do you mean by hexagonal submarine? o_o

Your character could climb into the submarine.

Hexagonal - shaped like a hexagon

sounds like Sink or Swim

or maybe In Search of Dr. Riptide?
