Throughout the game, the player can fly or drive through power-ups to collect them. These include rings that charge up the vehicle's shields, Smart Bombs, laser upgrades, wing repairs, and extra lives. Most stages also contain at least three gold rings - collecting three of these increases the vehicle's maximum shield level. If the player successfully collects three additional gold rings in the same stage, an extra life is awarded. Aside from the maximum shield boost, all power-ups carry over to the next stage. If the player runs out of lives, the game is over.
