As you make progress and fight of various tanks, flying crafts, ships, static guns and bosses power-ups come available. Power-ups include power capsules that increase your firepower (max four times) and a guided bomb that can be controlled after being deployed and damages enemies in a large area. The game can be played solo or with a friend.
