IGN: Shoot 1UP Hands-On

What sets Shoot 1UP apart from other 2D space blasters is that instead of using your extra lives one at a time you play them all at once. Each 1UP you collect will be added to your ship’s mass instead of waiting on the sidelines for you to eat a bullet. This way you are constantly gaining more firepower and defenses. The game isn’t over until every last ship has been destroyed.
