Astro Invader (1982) – Classic Shoot ’Em Up for Emerson Arcadia 2001 by UA Limited & Bandai

Astro Invader is a fixed-screen shoot ’em up developed by UA Limited and published by Bandai for the Emerson Arcadia 2001 home gaming console.

Released in the early 1980s, this title delivers a distinctive twist on classic space shooter gameplay, setting it apart from other arcade-style games of its time.

Players control a laser base that moves horizontally along the bottom of the screen, firing upward at descending waves of aliens. What makes Astro Invader unique is its column-based enemy formation. After being deployed from a mothership, aliens line up vertically in columns. Once a column fills, the lowest alien suicide-dives toward the player. If it reaches the ground, it explodes, creating a blast radius the player must avoid.

In addition to the column-based threats, UFOs occasionally appear at the center and sides of the screen. These must be destroyed on sight, as they pose an immediate threat—if they land, they will eliminate the player regardless of position.

The game ends when the player loses all three lives, requiring precision, timing, and awareness to survive increasingly chaotic waves.

The Japanese version, titled Kamikaze, features several key differences: more columns, center-only UFO appearances, and side-attacking regular aliens that do not follow the column pattern. Explosions from ground-crashing aliens are also significantly larger, increasing the difficulty.

Astro Invader stands as a creative and challenging entry in the Arcadia 2001 library. Its blend of strategic positioning and fast-paced reflex action makes it a standout among early home console shooters. For fans of vintage shoot ’em ups and obscure gaming history, this title offers both gameplay variety and international version insight.
