Street Fighter X Tekken (Japanese: ストリートファイター Ｘ 鉄拳 Hepburn: Sutorīto Faitā Kurosu Tekken?) (pronounced Street Fighter Cross Tekken) is a crossover fighting game developed by Capcom. The game was announced at the 2010 San Diego Comic-Con International by Capcom producer Yoshinori Ono. The game was released on PlayStation 3 and Xbox 360 on March 6, 2012 in North America and March 9, 2012 in Europe. The game features characters from both the Street Fighter franchise and Namco's Tekken series. As the game is being made by Capcom, with Namco being involved more in the licensing of the Tekken cast, the gameplay will be based on the 2D gameplay of Street Fighter as opposed to the Tekken series, and will feature projectile moves such as the Hadouken. Namco is currently producing their own take on the crossover, Tekken X Street Fighter, which will follow their 3D style of gameplay. The PC version will be released on May 11, 2012 in North America and May 14, 2012 in Europe, and the PlayStation Vita version is set for release in fall 2012.
Being developed by Capcom, the core gameplay is similar to that of the Street Fighter series, incorporating elements such as Super Combos, as well as EX Attacks from Street Fighter IV. Players each choose two fighters from the Street Fighter and Tekken series, both sets of characters are controlled using the Street Fighter 6-button system, however, it has been revealed that the Tekken characters will be able to perform Tekken style combos using the primary four buttons in a similar fashion to the Tekken 4-button system. These fighters can be switched out normally, or during certain combos. As fights go on, players build up power in a three sectioned meter at the bottom of the screen referred to as the "Cross Gauge", which allow the player to perform various techniques depending on how much of the gauge is filled, such as EX Attacks, Cancels, Super Arts and various Cross techniques detailed below. As opposed to the other crossover fighting games released by Capcom, in which the player must eliminate all the opponent's fighters to win, victory conditions are more similar to Tekken Tag Tournament, in which the first player to have one of their fighters' health bars reduced to zero loses the round, thereby the player who wins the most rounds wins the match.
The tag team element of the game is heavily emphasized, with players being able to switch between the two characters in their team in a variety of manners. Switch Cancel allows players to switch partners in the middle of a combo, whilst Cross Rush combos involve launching the opponent into the air before swapping partners and continuing the combo. Cross Arts, which require a full Cross Gauge, allows players to chain together each character's Super Combo in one straight attack, whilst the Cross Assault mechanic allows players to simultaneously control both characters in their team until the Cross Gauge runs out.
Street Fighter X Tekken features two new game mechanics: the Gem System and Pandora Mode. Players equip up to three gems to their characters, which provide different stat boosts depending on the type of gem. Six varieties of gems exist: attack, defense, speed, vitality, assist, and Cross Gauge. Each gem and its effects are designated by a specific color, and will activate as the players fulfill certain conditions during battle. When a character on a player's team has less than 25% health remaining, that character can be sacrificed in order to activate Pandora Mode, which gives the remaining fighter increased strength and an infinite Cross Gauge. However, this state has a time limit and the player will automatically lose if he/she cannot defeat the opponent before the Pandora state runs out.
The game will feature various online options. Two players can battle on the same team, one controlling each character, and face off in four player matches. Scramble mode allows four players to fight simultaneously in pairs of two. The game will also support online training modes which can be played competitively or cooperatively with two players, as well as support the Fight Request feature.
Other Capcom games will be referenced in the game, such as Dino Crisis, which has a stage based around one of its levels.
The center of the conflict between the Street Fighter and Tekken universes is a cubical object that crash-lands in Antartica. The object is of a mysterious origin and researchers worldwide are unable to determine what purpose it serves. The only thing that can be understood is that when beings come into conflict around this object, it releases a water-like energy that brings more power to the combatants. Due to the object's tendency to react to conflict between beings, they name it "Pandora". Whilst a standard story is given to most combinations of fighters, specific teams, such as Ryu & Ken or Kazuya & Nina, receive their own unique story elements and rival battles.
The following characters are available as playable characters in the game. The PlayStation 3 and PlayStation Vita versions feature 5 exclusive playable characters, including Cole MacGrath from Sucker Punch's Infamous series; Sony mascots Toro and his rival Kuro, who dress up as Ryu and Kazuya respectively; Pac-Man, who pilots a Mokujin-style mech; and Mega Man, who takes his appearance from the North American box art for the first game. Both Mega Man and Pac-Man became available as free downloadable content for the PlayStation 3 version on the 13th of March. Street Fighter's Dan, seen in the initial Street Fighter X Tekken reveal trailer, makes a non-playable appearance as the instructor in the game's tutorial mode.Ono stated that there is no exclusive character for the Xbox 360 version, claiming "We do have the exclusive characters for the Sony platform. We have Cole, the two Sony cats, Kuro and Toro. But basically for the Xbox 360, we were in discussions with them (Microsoft) for which character to put in as an exclusive, but we weren't able to decide on a character because of differences in timing and things like that." It was announced on February 21, 2012 that game will be released for the PS Vita in the fall and will include 12 additional fighters, 6 from each side. It was later confirmed that these 12 characters would be also released as DLC for the Playstation 3, Xbox 360 and PC shortly after the Vita's launch. All together, the Sony versions will have 55 playable characters available, giving Street Fighter x Tekken the biggest roster in a Capcom Fighting game (Vs. or not) since Marvel Vs. Capcom 2, which had 56 characters in all.
