Saint Dragon

The player controls the cyborg Saint Dragon, who has rebelled against the tyrannical Monster Cyborg army. Saint Dragon is initially armed with plasma bolts and fiery breath. By collecting tokens, the dragon's firepower can be upgraded with pulse torpedoes, a laser, bouncing bombs, ring lasers or a turret. Other tokens can upgrade the dragon's speed, weapon power, or initiate a "hyper" mode which endows maximum firepower and invulnerability. In addition, the dragon has an armoured tail which follows the player's movement, allowing it to be used as a defensive shield.
