First to beat all twenty levels wins! The faster you beat each level the faster the next level comes and the closer you get to beating all 20 levels first. If too many units get past you and you lose your lives you lose. If you have comments, questions, or suggestions, email me at bluemicrobyte@earthlink.net.
Pretty basic defense map, race everyone else to beat all 20 levels first. Not a whole lot of re-playability.
