Instant Blue Lander
At the start of the game, do not fire your standard gun. When the first Sart appears, fire at it with your Special Weapon. It will turn into a Blue Lander. You can collect the Blue Lander for an extra life, or you can shoot at it until it becomes a Red Lander. Red Landers give you an extra life as well, but they also increase the rate of your automatic fire. See the items page for more information.
Instant Level 5 Guns
Shortly after the game begins, a trio of Boxes will appear after you have destroy some of the Duster rocks. If you are playing the game for the first time since turning your system on, it's a safe bet that the middle box contains a Power Chip. If you ram into this box, you will automatically upgrade your weapons from level 0 to level 5. If you are starting a new game after a previous game, there's no guarantee that the Power Chip will be contained in the middle box. Which box contains a Power Chip, is determined by your score When you destroy 2 yellow Dusters at the start of a game, it's guaranteed that the middle one contains a Power Chip. See the items page for more information.

Numerous sets of Boxes
Boxes set in three appear after killing a certain number of enemies. Since enemy bullets count as enemies too, you can place yourself in front of Mortar to destroy its stream of Sigs. Your starting weapon is enough to hold the large amount Sigs back. However, this causes lots of sets of Boxes to appear.
