A couple of videos have popped up over on YouTube showing upcoming characters and their game play for Netmarbles Marvel Future Fight. So far it looks as if Maximus, Crystal, Gorgon, Karnak, Inferno, and Moon Girl (& Devil Dinosaur!) are being added to the game. It also looks like there are new costumes for Ms. Marvel, Black Bolt, and Elsa Bloodstone being added as well. No official announcement yet on when it goes live in the US (that I have been able to find), but hopefully we will have more information soon.
Seeing my favorite Inhumans added to the game has definitely given me incentive to go back.
The first video shows primarily Crystal, Moon Girl, and Maximus in action. The second adds Inferno, Karnak and Gorgon to the mix.
