Here's the announcement trailer.
His most recent videogame appearance was in another Capcom game Ultimate Marvel vs. Capcom 3, where his appearance was modeled from his character design in the aforementioned Strider 2 (which was consequently used for his character design in the first Marvel vs. Capcom). His looks in this new game resembles his old design, albeit with noticeable updates.
The year is Meio: 048, on an alternate dystopian future of Earth. The whole planet suffers under the oppressive, iron-fisted rule of the mysterious and omnipotent Grand Master Meio. An expert in sabotage and assassination, Hiryu is the youngest ever recruit to attain a Special A-Class in the hellish Strider training program, and is the only man capable of achieving the mission to eliminate Grand Master Meio.
