Soulcalibur (ソウルã‚ャリãƒ) is a weapon-based 3D fighting game developed by Project Soul and produced by Namco. It is the second game in the Soul series, preceded by Soul Edge in December 1995. Originally released in arcades in July 1998, it ran on the Namco System 12 hardware. It was ported to the Dreamcast in 1999 with new features and improved graphics. The North American version was released in September 1999 as a launch title for the Dreamcast and was part of the successful launch of the new console. It became available as a downloadable title on the Xbox 360's Xbox Live Marketplace in July 2008. A sequel, Soulcalibur II, was released in July 2002. Developed closely with Namco's Tekken development team, it is one of few home console ports that outdid their arcade parent graphics-wise. The title brought many innovations to the fighting game genre that include a heavy emphasis on weapons. Soulcalibur is widely regarded as one of the best Dreamcast titles and is one of the most critically acclaimed fighting games of all time.
