These additional weapons can be selected at the radar bases. Only one type of weapon can be equipped at any time.
LOCK ON[edit | edit source]
This choice enables the tank to launch missiles. When a target approaches, the B button can be pressed to lock onto the target. Once the tank is locked onto a target, the tank's movement changes to encircle the target instead of the normal control scheme, allowing the player to easily attack the target from behind. This lock-on also applies to the laser beam weapon, so it also becomes easier to hit the target with lazers. The display will read "OBJECT LOCKED" when a target is within aiming distance, and pressing the B button during this display will fire a missile. However, missiles will not switch directions to pursue a moving target. Firing a missile, pressing the SELECT button, allowing the target to move out of sight, or moving very far away will release the target lock.
BOMB[edit | edit source]
Bombs are needed to destroy the underground tunnels constructed by the enemy. Pressing the B button while the VIXIV is in the air will drop a bomb, but this can only be done upon orders issued by the mission commander. It can also be used while the tank is on the ground, where the bomb is fired into the air and makes a cylindric explosion (which also affects enemies in the air) upon hitting the ground. The player loses two blocks of shield health if the tank is caught in the bomb's explosion, so the bomb should be fired while running the tank in the reverse direction to avoid unwanted damage. Only one bomb can be carried at a time, so the tank must return to the radar base after each use to re-equip a bomb.
JETPAC[edit | edit source]
This choice is not a weapon, but makes getting up in the air much easier. When equipped, the player can lift off into the air just by pressing the B button at TURBO speed instead of looking for slopes to lift off. Fuel is still required to put the tank in TURBO speed. Pressing the B button at lower speeds will cause a slight "jump" in the tank's movement.
HIGH-EX[edit | edit source]
This is the final weapon designed for use in the last mission of the game. The weapon does not need to lock onto any target, and pressing the B button launches a gigantic missile which causes a huge cylindric explosion. However, 8 missiles are needed to fire the weapon, and the VIXIV will always get caught up in the resulting explosion, losing 8 blocks of shield health. This requires the player to have full shield health and a full arsenal of missiles when using the weapon.
