Dark Side is a 1988 video game published by Incentive Software for the Amiga, Atari ST, Amstrad CPC, Commodore 64, IBM PC compatibles, ZX Spectrum, and Sharp MZ-800.

A targeting crosshair displayed in the helmet's HUD allows the player to fire the suit's weapon at specific locations.

When the shield's charge is depleted, the player is vulnerable to enemy fire and simply bumping into walls can end the game.

There are a number of "recharge" points (in the form of columns) hidden in the game where the player can replenish the suit's energy supply.

Dark Side was the second game to use the Freescape engine, which allowed the production of full three-dimensional environments using filled polygons in which the player could move around freely.
