There are eight types of weapons to use, and each can be powered up by collecting chips (small egg-shaped items). Picking up chips causes the player's current weapon to level-up, to a maximum of six. There are two types of chips to find; Orange chips contribute to a level-up, but at higher levels, more chips are required to reach the next level. Green chips make the weapon level up instantly. Each weapon has a function that can be manipulated with the Shot-Control button, changing around the weapon's abilities to suit different situations. Switching to another weapon is done by picking up a numbered item, with initials representing one of the eight weapons.
