ALCON

ALCON

Overview & History

Released by Taito in 1986—and later distributed internationally under the alternative title Slap Fight—ALCON is a vertically scrolling shoot-'em-up that challenged players with relentless interstellar warfare. Set in a distant future, the storyline thrusts you into the cockpit of the SW4 interstellar fighter craft, tasked with single-handedly dismantling the tyrannical alien armada occupying the galaxy. Unlike many of its contemporaries that relied on rigid linear power-up systems, ALCON pioneered a dynamic upgrade economy. As you obliterate enemy squadrons, they drop star-like items that fill a tactical progress bar at the bottom of the screen. Players must strategically cycle through and lock in specific abilities—ranging from wide-spread plasma blasts and homing missiles to speed boosters and defensive shields—tailoring their ship's loadout on the fly to survive brutal, wave-clearing boss encounters across diverse planetary atmospheres.

Gameplay Features & Mechanics

ALCON distinguishes itself through its relentless pacing and clever scoring mechanics. The game introduces a unique 'extend' feature and point multipliers that reward precise, aggressive play rather than passive survival. Graphically, it showcases vibrant, detailed sprite work for its era, depicting sprawling alien landscapes and massive, multi-tiered enemy capital ships that fill the display. The difficulty curve is notoriously steep, demanding memorization of enemy spawn patterns and rapid tactical decisions regarding your power-up allocation.
