Laser Tank Duel is a 2 player only tank battle game... strangely enough with only keyboard controls. Because of this (and from when it was written), it pretty requires the Coco 1/2 keyboard layout (one player uses up/down arrows, Q, W and Z for movement and firing, and the 2nd player uses left/right arrows, P, ';' and '/' keys). The players have 4 way movement to go down the corridors and try to shoot each other. The game ends when the first player gets to 8 kills. Aside from the two players, there are also 8 absorption mines that float around (and sometimes stop); these can not harm either of the players (and can be driven through), but they will absorb the player's shots, stopping them before they hit the edge of the screen.
