A Jax

AJax is a vertically scrolling shoot ’em up arcade game released by Konami in 1987. The players control a “Tom Tiger” helicopter (in the 2D stage) and later a “Jerry Mouse” fighter jet (in the 3D stage), and shoot enemies in the air and bomb them on the ground, collecting power-ups and defeating bosses to advance levels.
The game takes place in a fictional 2007 where the Earth has been conquered by alien invaders. The player combats the occupation forces using vehicles under operation code named ‘A Jax’ created to liberate the Earth. Game play is divided into two scrolling sections with two different vehicles: the first being a vertical scrolling section with the helicopter and a Rail scrolling stage with the jet/space fighter. The game spans eight stages and extends are set to 30,000 and a second at 150,000 points.
A basic vertical shooter. Use your helicopter/jet to destroy enemies both in the air and on the ground using machine guns and missiles.
Destroy the red enemies and collect the power-up capsule. The letter on the capsule determines which enhancement is available:
• V – Vulcan: Rapid bullets can be fired in the directions controlled.
• B – Bomb: Air-to-ground missiles will have extra power.
• 3 – 3-Way: Fire bullets straight forward, straight right and left
• T – Triple: Bullets spread three ways in front.
• L – Laser: Radiate double laser
Destroy the red enemy formation and collect an “O” power-up capsule for extra firing power.

During the helicopter segments, the player has access to four different weapons including the Vulcan, Bomb, 3-Way, Triple and Laser. Each weapon is available through their own specific pick-up icon. However, the helicopter can only equip one firing weapon at a time with the Bomb being constant. The player also has access to Options which add additional firepower. The jet segments contrast highly from the helicopter segments in the complete lack of available power-ups and additional weapons beyond a machine gun and bomb.
