Bio Menace

The object of the game is to lead the main character Snake Logan to the exit of each level. In most cases the exit is blocked off by an energy field which will kill Snake instantly if he touches it, and must be turned off with either a keycard obtained when rescuing the level's hostage or a crystal shard acquired by killing the level's boss, depending on the level.

As is typical of the run and gun genre, the player character can walk, jump, shoot, and crouch. In addition, Snake can use grenades and land mines, which appear as pickups. Weapon powerups consist of machine guns (which allow sustained firing), plasma guns, and super guns. Except for the plasma gun, all of Snake's guns are hitscan, including the default gun.

Bio Menace was called Bio Hazard during production. It was planned for release on November 15, 1991.

The game was reviewed in 1994 in Dragon #202 by Sandy Petersen in the "Eye of the Monitor" column. Petersen gave the game 2 out of 5 stars. The reviewer of the German magazine PC Games praised the behavior of animated enemies, the lack of movement jerks and noted a fast scrolling in all directions of movement. A shareware game reviewer of PC Review magazine commented that Bio Menace's animation of biomonsters differentiates it from Duke Nukem, but also noted that "Apogee needs to come up with something new".

In a retrospective review, a reviewer at Hardcore Gaming 101 praised the look of the game, noting that thanks to the Commander Keen engine, the game does not have the annoying stiffness of the era, and the control is satisfying. However, he also called the music a weak spot, and that Bobby Prince, who later wrote the Doom soundtrack, did not show his strong side here.

Apogee released the game as freeware on December 23, 2005, as a "Christmas present", and the full game can be downloaded from the Apogee website. In October 2014, 3D Realms released 3D Realms Anthology, which includes Bio Menace.
