Gunstar Heroes

Unlockable: Unlimited Health Power Ups
In Level five, be on the lookout for the last power up pod that shows up. If you go too fast you'll miss it. That power up pod drops health power ups. Unlike the usual ones where they drop only about 2 or 3. This one keeps dropping power ups every time you kick it. You can gain vitality points of up to 999! Be careful though as the enemies can destroy this pod!
