Gameplay
Super Robot Spirits is a 3D fighting game that pits players in one-on-one battles against mecha from select Japanese anime series. Spirits includes seven playable characters from the start: Shining Gundam from Mobile Fighter G Gundam, Daitarn from Invincible Steel Man Daitarn 3, Dunbine from Aura Battler Dunbine, Voltes V from Chōdenji Machine Voltes V, Walker Xabungle from Combat Mecha Xabungle, Dancouga from Dancouga. Super Beast Machine God and R-1, a robot created by Banpresto specifically for this game. There are also three unlockable characters that can be played once certain conditions are met.
The game is presented from a 2.5D perspective; While the characters and environments are rendered in 3D, the gameplay takes place on a 2D plane. Each character can kick, punch, block incoming attacks, and use weapons such as turrets and energy swords. In each battle, which depicts anime episodes, the player must defeat his opponent by depleting his health. Hitting opponents provides the player with "spiritual abilities", which fill an orange gauge below their health bar. Spiritual abilities are used to unleash a powerful super attack, which opponents cannot deflect. Super attacks differ for each character and are stronger depending on the amount of spiritual abilities the player possesses, and are different for each character. The player can also combine their weapons with an attack to cause a different super attack to develop, which varies depending on the selected character.
