As of right now, there's a Closed Beta running for Marvel Heroes, an upcoming action RPG/MMO staring many of your favorite Marvel heroes and villains! If you've ever played action RPGs like Diablo and Torchlight, and had lots of fun playing X-Men Legends 1&2 as well as Ultimate Alliance 1&2, then you'll want to check this out!
With over 25+ heroes so far announced (and many more to come!) and an exciting plot (written by Marvel's own Brian Michael Bendis) that centers around Dr. Doom aspiring to harness/control the powers of the Cosmic Cube, thus forcing our heroes to travel through various locations in the Marvel Universe (Avengers Tower, the Savage Land, and Mutant Town to name a few) to halt his plans of universal domination! Additionally, each hero will also have customizable visuals and accessories to outfit themselves with, as well as many different options for skill selections/specializations.
This game looks like it's going to be pretty promising! So what are you waiting for? Sign up for the Closed Beta now! And don't despair if you don't get selected; the final product will be ready to play Spring 2013. Hope to see you there!
