Battle Fantasia is a fighting video game developed by Arc System Works and development was headed by Emiko Iwasaki, who had previously served as illustrator for the company's Guilty Gear series, and utilizes three-dimensional character models restricted to two-dimensional battlefields.
Battle Fantasia is a traditional two-versus-two fighting game using a variety of characters, each with their own special attacks and fighting styles. Players face each other in best-of-three round battles that involve the use of normal attacks, throws, and special moves that often involve combinations of button presses and directional input, which can be strung together in long combo strings.
The game features four main attack buttons - two punches and two kicks - as well as a fifth "Gachi" button used to parry incoming attacks. If a player times a Gachi command just as an opponent's attack lands, it negates all damage and allows the player to counterattack in a brief time frame. The button can also be used to push an opponent back when combined with a direction, as well as allow the player to recover faster from a knock-down.
As players deal and receive damage, they add to their MP Gauge located at the bottom of the screen, which can be stocked to a maximum of three levels. Players can expend MP to activate their "Heat Up" mode to increase their strength and add additional effects to their attacks, with specific enhancements differing with each character. The gauge also allows characters to unleash powerful super moves which cause heavy damage but require spending one gauge level to activate, and can be strung together with special moves with proper timing resulting in a Super Cancel combination.
