Fighting Vipers is a 3D fighting video game developed by Sega AM2. It uses the same game engine as AM2's Virtua Fighter 2 but features enclosed arenas and an armor mechanic, and was targeted more towards Western audiences, using a U.S. setting and more freeform styles of martial arts. The game was released in the arcade in 1995 using the Sega Model 2 hardware. The game was ported to the Sega Saturn, and to PlayStation Network and Xbox Live Arcade in 2012. Though Fighting Vipers was not very popular in North American arcades, the Saturn version was one of the most high-profile games in the system's 1996 holiday lineup, and was met with positive reviews.
