Nano Tank is a little-known gem for Windows that features cleverly (some will say fiendishly) designed levels with electrical components. The goal in each level is simple: maneuver your nano tank to the exit. The method, however, is arduous: you must power the exit, and manipulate devices such as batteries, switches, and relays to form a powered track for the tank. You must also avoid a trace bug that moves along traces and can destroy your tank. It's not as elegantly designed as Elements, which is based on similar concepts, but is still a fun and challenging game with a neat plot (destroying an alien computer) to boot. Two thumbs up!Reviewed by: Underdogs
