Let me say straightaway that you may be disappointed with the representation of the gunslingers. That apart though, the graphics are fair enough - purple rocks, green trees and yellow cacti.

Essentially this program is intended as a two player duel, though the computer will act as a stand-in. Start by selecting the duration of combat, up to nine minutes, then jocket for position and pump in some killer shots. Seek cover behind a cactus at your peril, for they can be shot away, and beware of bullets ricocheting off rocks. It goes without saying that respective tallies are displayed continuously.

With a different layout for each contest, and decent sound effects, this tape should find itself on plenty of shortlists.
