Choose a mech out of six available types with five being humanoid Virtua On style bots and one being a tank-bot. Each mech has it's own particular strengths such as speed, agility and firepower as well as weaknesses. Once you've chosen your warrior, you'll outfit it with a host of weaponry and body parts to help it in battle. Parts may be upgraded later for higher performance. Program your mech and put it through the battle sequences against opponents. Programming is done by way of simple icons and commands. Fairly simple learning curve with a mixture of Japanese and English text in the menu system.
