We had a chance to play with both characters, which have very different fighting styles. Nightwing is primarily weapons-based, wielding a staff that has a extended reach for sweeping and poking attacks. He's also noticeably nimbler than other fighters and can leap out of danger when backed into a corner.

Nightwing's staff can be split in two by pressing the special button -B on an Xbox 360 controller increasing his speed and jump height, but decreasing his range. Nightwing's weapon stance change opens up a new set of attacks and special moves for the character

Cyborg's fighting style includes a series of powerful hand-to-hand attacks complemented with long-range attacks: lasers, fireballs and missile strikes. Using the game's mechanic of high, mid and low attacks, Cyborg can launch missiles straight into the air, shoot fireballs forward and emit energy blasts at an opponent's feet (then follow up with a pair of lobbed, shoulder-launched missiles). Cyborg's special again, with the Xbox 360 controller's B button is a health regenerating move, ensuring that opponents must stay offensive when fighting him. His charged up super move consists of a hefty, oversized punch followed by a screen-filling energy blast a la Iron Man's super move from Marvel vs. Capcom 2.

The two characters join a thus confirmed roster of: Batman, Superman, Wonder Woman, Flash, Solomon Grundy and Harley Quinn.
