Short answers, pulled from the story.
Capcom Fighting Evolution is a 2004 crossover fighting game developed and published by Capcom. It originally released for arcades on Namco System 246 hardware, then was ported to the PlayStation 2 and Xbox.
The game features characters from Street Fighter II, Street Fighter Alpha 3, Street Fighter III: 3rd Strike, Darkstalkers 3, and the CPS III arcade game Red Earth. Each character uses the fighting system from their original game.
Ingrid is the only original character in Capcom Fighting Evolution. She was originally intended to debut in the cancelled 3D fighting game Capcom Fighting All-Stars, and her ending reveals she is the Goddess of the Sun. She later appears as a time traveller in Street Fighter Alpha 3 MAX for the PlayStation Portable.
Critics and fans criticized the game for reusing character sprites with drastically cut-down animation frames, omitting moves characters originally possessed, and leaving fan favorites like Ken, Sagat, and Morrigan to cameo roles only. Producer Yoshinori Ono acknowledged that mixing six different fighting systems created significant balancing problems.
The soundtrack was released in Japan on the 12th of December 2004 under the title Capcom Fighting Jam: Original Soundtrack, with music composed by Noriyuki Asakura and cover art by Shinkiro. The first pressing included an exclusive mini disc featuring Ingrid's theme, "Heat Haze," performed by Maiko Kubo.
