Injustice: Gods Among Us from the Mortal Kombat team adds two new DC heroes.

Two new characters have been added to NetherRealm Studios' new DC Universe fighting game, Injustice: Gods Among Us. DC favorites Cyborg and Nightwing were unveiled at Comic-Con today, joining the already announced roster of Batman, Superman, Harley Quinn, Solomon Grundy, Flash and Wonder Woman.

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.

We'll have more from Injustice: Gods Among Us, including an interview with creative lead Ed Boon, later this week.

Injustice: Gods Among Us is slated for release on the PlayStation 3 and Xbox 360 in 2013.
