Earlier today Capcom came through with more info on Marvel vs. Capcom: Infinite, including a release date, additional characters, and a new story trailer.
There’s also a 2017 Character Pass, which grants access to six post-launch characters, including Sigma.
Let’s start with the latter, which shows what happens when Mega Man X villain Sigma gets in on world domination and the power of the Infinity Stones with Marvel’s Ultron.
