one and a half minute each, with substitutions allowed at half time. Virtua Striker 4 also adds a qualifying match, which grants access to the tournament proper if won. The game operates with three buttons: one for passing (which is also used for sliding tackles when not in possession of the ball), one for long balls (which automatically crosses if the player is running parallel to the box) and one for shots, which can be charged or, if the player is on the receiving end of a cross, tapped for a header or volley finish. The Start button is used to alternate between each team's two available tactical schemes before and during a match (except for the first game, which had no such mechanic, as each team came with its own preset formation) - while each has an offensive or defensive mentality, the formation of choice before kick-off will influence in which formation the team will adopt a neutral mentality. Virtua Striker 4 also added a sprint button. The series has been ported to consoles on two occasions: Virtua Striker 2 for the Dreamcast (released in Japan and Europe as Virtua Striker 2 ver. 2000.1) and Virtua Striker 2002 for the GameCube (released in Japan and Europe as Virtua Striker 3 ver. 2002). Virtua Striker was also featured as a minigame in Sega's PlayStation 2 EyeToy-based game, Sega Superstars. The first three games of the series (counting also the Virtua Striker 2 revisions, but not the 2002 revision of Virtua Striker 3) feature a hidden team called FC Sega, made up of the game's developing staff, which always faces the player's team in special matches after the player wins the final match, and can be selected through a special cheat code.Virtua Striker 2 features two other hidden teams in addition to FC Sega: MVP Yukichan and MVP Royal Genki (exclusive to Version 2000.1), both of which consist of strange, cartoonish characters. The original team selection BGM from the first game also exists, and can be heard through a special code. In Virtua Striker 3 and the GameCube port, ver. 2002, there is an unlockable team called FC Sonic. This team is made up of Sonic, Tails, Knuckles, Amy, Dr. Eggman (who plays as the goalkeeper), four Neutral Chao, a Dark Chao, and a Hero Chao, and has Sonic's creator, Yuji Naka, as manager.Virtua Striker 4 was released on the Triforce
