Aside from the usual retail copy of the game, Capcom has also revealed a special edition for $69.99. The special edition (shown above in glorious fashion) will include some rather interesting goodies such as two bonus characters (Jill Valentine of the Resident Evil series and Shuma Gorath from the Marvel universe). The set also includes a steelbook case with exclusive art work, a comic/art book that serves as a prologue to the game, a one-month subscription to Marvel Digital Comics, and two playable DLC characters (mentioned above) that will be available four weeks after the launch of the game.
As of now, two new characters for Marvel vs. Capcom 3 have been announced yesterday, which are Zero and She-Hulk (trailer reveal here). We'll have more news on the various character reveals as the weeks go by, so stay tuned.
