Based on the Heavy Metal comics magazine, Geomatrix features a dark and gritty aesthetic that combines sci-fi with fantasy locales. While it's not based on any story in the Heavy Metal universe, it features both consultation by the then-owner of the magazine (comic book artist Kevin Eastman) and character designs by comic book artist Simon Bisley. It also features a licensed soundtrack by heavy metal artists (including Megadeth, Halford, Corrosion of Conformity, and Dust to Dust).The story takes place in the late 21st century, where evolution in Nanobot micro-robotic technology allowed people to abandon the real world for cyberspace. Due to a catastrophic event that floods most of the Earth's landmass, power wars between multiple gangs began (using cyberspace as the battleground).The game is seen as a spiritual successor to Spawn: In the Demon's Hand, now with more fighting game elements (such as a traditional round-based system) and less loadout management (with each character only having one weapon, including swords and both small and large firearms, which can be swapped as pick-ups). The game features two-player split-screen multiplayer (for both co-operative and versus play), with the option for two machines to be linked for team matches.It was later ported to the Dreamcast in Japan (on July 12, 2001), North America (on September 13, 2001), and Europe (by Bigben on April 12, 2002).GameplaySimilar to Spawn: In the Demon's Hand, the game is a one-joystick, four-button game. However, players now have two attack buttons (Shot and Attack) along with the Jump and Target Lock-On buttons.Teams & CharactersThere are 12 playable characters, each split into four teams:818 StompersA mysterious gang of punks who stop at nothing to further their goals.
