The trailer for “Marvel vs Capcom: Infinite” has been released online, giving fans a look at the storyline of the upcoming crossover fighting game. The trailer also revealed that the game will be released on Sept. 19.

The story trailer for “Marvel vs Capcom: Infinite” reveals that Avengers foe Ultron has teamed up with “Mega Man X” antagonist Sigma. The two robotic villains have found a way to fuse into one entity using the Infinity Stones to become Ultron Sigma.

Although Ultron will be available as a playable character right away, Sigma can only be purchased through the Character Pass DLC, according to Kotaku. There’s no word yet on how much the DLC pass will cost.

The “Marvel vs Capcom: Infinite” trailer also confirms some of the other playable characters like the Hulk, Thor, Hawkeye, Chun-Li, Strider Hiryu and “Resident Evil’s” Chris Redfield. The end of the trailer also shows a short appearance by “Guardians of the Galaxy’s” Rocket Raccoon. The first batch of characters that were confirmed at last year’s PlayStation Experience were Captain America, Captain Marvel, Iron Man, Mega Man X, Morrigan and Ryu.

“Marvel vs Capcom: Infinite” is confirmed as having a standard edition ($59.99), a Deluxe Edition ($89.99) and a Collector’s Edition ($199.99). The Collector’s Edition includes four interlinking TriForce dioramas of Mega Man, Chun-Li, Captain Marvel and Iron Man, and a case containing LED-powered Infinity Stones.

Both the Deluxe and Collector’s Edition also include additional costumes and the Character Pass DLC. Capcom says that there will be six post-launch characters including Sigma.

“Marvel vs Capcom: Infinite” is now available to preorder and will be released on Sept. 19, 2017 for the PlayStation 4, Xbox One and Windows PC. Confirmed game modes include the “cinematic” Story Mode, Arcade, Training, Mission and “various” multiplayer modes.
