Sink the U-Boat © 1980 L&M Soft.
Did you get the opportunity to sink any U-boats during World War II? Probably not, so here's your chance to do battle with a German U-boat. Battle is done on a large grid where a game of elimination is played with the computer. Excitement builds the longer the game lasts.
Published as a type-in program that can be typed into Bally BASIC.
Later re-released on tape as "Tape 11: Sink the U-Boat + Rescue Air Drop".
