Capcom vs. SNK 2 EO is a crossover fighting game available on Xbox, featuring an Easy Operation system that simplifies controls. It introduces four bonus characters: Evil Ryu, Orochi Iori, Shin Akuma, and Ultimate Rugal. Players can choose from various Grooves that alter gameplay mechanics, including the EO-ism control scheme. The Xbox version supports online play for two players and offers progressive-scan graphics.
Capcom vs. SNK 2 EO is the same game but with minor changes in gameplay and the inclusion of an EO (`Easy Operation`) system that allows the player to perform specific attacks by simply moving the right analog stick in a certain direction. Like all other home versions of the game, CvS2: EO also contains four bonus characters: Evil Ryu, Orochi Iori, Shin Akuma (Shin Gouki in Japan), and Ultimate Rugal (God Rugal in Japan), powered-up versions of four regular characters.
Before selecting a team, the game offers a selection of `Grooves`, which change the way the game is played, as well as `AC-ism` or `GC-ism` Grooves; GC-ism simplifies the control scheme, originally designed for the GameCube gamepad. In the Xbox version it is called EO-ism. Capcom vs. SNK 2 EO also removed the Roll Cancel glitch that was in the original versions. In addition, the Xbox version of CvS2: EO also included online play for up to two players on Xbox Live as well as progressive-scan (480p) support, which was noticeably absent in the PlayStation 2 version.
