Bio Menace is a 2D, side-scrolling, platform game developed and published by Apogee Software for DOS. It was set for release in November 15, 1991 but due to re-configuring the engine that was used in Commander Keen in Goodbye, Galaxy, it took two years to develop. It was built on a licensed version of id Software’s Commander Keen game engine, and was known as Bio Hazard during production. Apart from the engine and music, all in-game content was created by the game’s designer, Jim Norwood. In 2014, the game was re-released on Steam, and in 2015 on GOG.com with support for Windows, Mac OS, and Linux.
The player controls the protagonist, Snake Logan, a top CIA operative. Upon receiving reports of Metro City being invaded by mutants, Logan is ordered to fly recon over the city. However, after crash landing in Metro City, Logan is forced to complete his mission on foot.
