Boat © 1973 DEC [Digital Equipment Corp.]
The goal is to destroy a gun boat controlled by the computer. Each turn the player can fire at the boat. The player must hit vulnerable parts of the boat twice, or once and two additional hits to win. Once the player misses the gun boat will fire back and try to destroy the player's submarine. After each hit a text-mode graphic of the gunboat is shown.
