Altered Beast - Versions

Versions

Altered Beast was produced as a standard upright only with custom artwork on the cabinet. In most versions, the game's controls consist of an eight-way directional and three buttons, one each for "punch", "kick" and "jump". The game has single player and cooperative two-player modes. One of the more well-known features of Altered Beast is the use of voice samples, such as Zeus saying "Rise from your grave" and Neff's "Welcome to your doom!".

Altered Beast was ported to several platforms after its original release in 1988. It was released for Sega Master System, PC Engine, PC Engine-CD, Famicom, Atari ST, ZX Spectrum, Commodore 64, Amstrad CPC, Commodore Amiga and DOS. The Sega Mega Drive/Genesis version is noteworthy for being the original pack-in game for that system in North America, Europe, and Brazil, before being replaced by Sonic the Hedgehog. A hand-held version of the game, made by Tiger Electronics was released in 1988.

The Mega Drive version is included in the compilations Sega Smash Pack, Sega Genesis Collection and Sonic's Ultimate Genesis Collection, with the latter two also including the arcade version as an unlockable game. The Wii's Virtual Console service offers emulated versions of both the arcade and the Mega Drive port, while the Xbox 360's Xbox Live Arcade and the PlayStation 3's PlayStation Network have a re-worked arcade version with HD support, online leaderboards and network play. Sega released an official iOS port of the Mega Drive version in late 2010, played on the iPhone and iPad.

Certain differences are seen between the several versions of the game. Some of them, like the Master System one, were only single player and had only four levels. Others provided different beasts to mutate into, such as a humanoid lion or a shark form seen in the NES version.
