This is a vertically scrolling SF shooting game released in Japan by COMPILE in 1987.

Story-wise, it serves as a sequel to the MSX version of “ZANAC”, with players piloting the cutting-edge AFX-6502 “ZANAC” to battle against organic intelligence. The AFX-6502 “ZANAC” is equipped with both a standard shot and special weapons. By collecting numbered chips that appear during combat, players can switch special shots, and by collecting the same chip consecutively, they can enhance their special shots.

The variety of special shots includes piercing rounds that take down multiple enemies in a row, omnidirectional shots that fire in eight directions—common in shooting games—as well as defensive barriers, vibrating shots that move rapidly left and right, and rotating shots that spin quickly around the player’s ship. Whether switching between different shots depending on the situation or focusing on strengthening a preferred special shot, players can tailor their playstyle for an optimal experience.

A defining feature of this game is the ALC (Auto Level Control) system. In ZANAC EX, the intensity of enemy attacks dynamically adjusts based on how players progress through battles. Destroying enemy fortresses or shooting down reconnaissance units, for example, weakens enemy assaults. This system ensures that every playthrough unfolds differently, keeping the gameplay fresh and engaging.
