Zone of the Enders: The Fist of Mars for Game Boy Advance is a real-time strategy game with a healthy dose of action to keep you on your toes.

The year is 2173 and humans have colonized Mars and Jupiter. There is constant conflict between the Earthlings and space-wanderers called Enders. Konami serves up a hefty story loaded with such familiar sci-fi trappings such as artificial intelligence, high-speed space travel and alternative energy sources.

During more than 20 combat scenes, you control a variety of vehicles, including tanks, human controlled robots called LEVs and super advanced robots called Orbital Frames. Each vehicle has its own unique anime-style attacks and can be upgraded and tweaked to your liking.

As you move throughout the square grid maps you can perform both short- and long-range attacks. Once an attack is initiated the perspective changes to a first-person mode and you must move your crosshairs frantically to either dodge or attack the enemy.

Between these battle scenes, the story unfolds through long dialog sequences. You can also tinker with your units by purchasing upgrades and customizing weapons. The variety of vehicles and weapons will keep you busy for hours, but the story sequences may test your patience.

Zone of the Enders: The Fist of Mars gives Game Boy Advance owners a deep real-time strategy game with a unique battle system.
