Smashing The Battle: Ghost Soul is an enhanced version of the hack-and-slash action adventure game Smashing The Battle that adds a "Ghost Soul" sequel that doubles the volume and new heroines designed by Mana Kakkowarai.

Players will fight against enemy robots using standard and combination attacks to open an escape route and clear the stage. By hitting the enemy with specific attacks, players can build up skill points to unleash special moves that can damage a large number of enemies at once. Coins obtained by clearing the stage can be used to upgrade characters, as well as to change into additional costumes with various functionalities.
