BBS Submarine Game

[hidiver808]

I'm trying to find an Ascii game that I played on my local BBS back in the late 80s. You controlled a submarine and the goal was to get close to the enemy coast without being detected and launch your weapons. It was purely ascii. I mean the graphics were all ascii characters. You controlled your sub by typing in text commands like d100 to move your sub to a depth of 100. Sound familiar to anyone?
