Although the only way to move in the game is on foot, once Roll Caskett repairs a support car, she is able to directly take Mega Man to specific areas. In "Legends", large gems called Refractors are used as a power source. Small shards of them can be exchanged for money, and in the game, enemies that are destroyed will often drop these Refractor Shards. When shards are picked up, the equivalent amount of Zenny, the game's basic unit of currency, is added automatically. The health of Mega Man can be increased through the game in the shops, while it can be recovered through packs bought at shops, obtaining red spheres from defeated opponents or by asking the character Data to recover Mega Man's health. Mega Man also has a Life Shield which reduces the damage that he can receive from enemies. The damage caused by enemies can also be reduced by obtaining upgrades to Mega Man's armor or his helmet. Mega Man's interactions with characters from the game can also affect the price of objects. If the player makes Mega Man be rude with characters, prices from objects will be increased and the dialogues with people will also change.
