 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 2 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.
 Box roulette
Knowing the contents of 3 boxes will help you to upgrade your Zanac more quickly. Boxes that come in sets of 3, come in groups as follow:
- 1 Empty Box, 1 Power Chip Box, 1 Lead Box.
- 2 Lead Boxes, 1 Power Chip Box.
- 3 Empty Boxes
- 1 Lead Box, 2 Power Chip Boxes. Lead box is in the middle in this case.
Knowing the contents of 2 will usually determine the contents of the third box so you can determine if it's safe to ram into or not.
|First Box||Second Box||Third|
|Red||Red||Third Box is empty.|
|Red||White||Third Box contains a Power Chip.|
|White||White||Third Box contains a Power Chip.|
|Power Chip||Red||Third Box contains Leads.|
|Power Chip||White||Usually Third one contains Leads, but can also be another Power Chip, especially if the Power Chip Box wasn't the middle one.|
|Power Chip||Power Chip||Third Box contains Leads.|
 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 numerous sets of Boxes to appear.
