The game will be available in two versions. The main version is a downloadable freeware version for DOS, Windows, PSP, Playstation 2, Dreamcast, and GP2X. The game will also be available in a commercial special edition for the Sega Dreamcast video game console.
The special edition was announced in 2006. However, although it hasn't been officially cancelled, it is considered on hold as no new information has been released since its announcement.
Unlike their previous game Beats of Rage, Age of the Beast will feature "original graphics and sound, plus an improved game engine".
The Dreamcast version was listed as one of the "upcoming [Dreamcast] projects [to look] forward to" in the eighth issue of the British print magazine, Retrogamer.
According to the press conference held by Dan Loosen of the GOAT Store at the Midwest Gaming Classic on June 3, 2006, the engine will be customizable similar to the engine in Beats of Rage, except that it will feature more moves, the ability to ride animals, up to 4 simultaneous players, and a customizable palette for each character. The freeware release will include the full engine, but the freeware game included with the engine won't use as many features as the commercial release. The commercial release will have more features, characters, and unlockable features.
