The Ultimate Marvel vs. Capcom 3 achievements list was released on xbox360acheivements.org. The reason why this in particular is so special is because the list contains icons with the leaked characters in them.
The characters look like they are in the form of their actual in-game model and it gives you a little sneak peek at what you'll be looking at when the game is released. This includes all the leaked characters including Vergil, Frank, and Rocket Raccoon.
Batsu Ichimonji and Bishop from the X-Men are joining the fight in Ultimate Marvel vs. Capcom 3 through a recently created mod for the game.
Dual Pixels: "After Marvel vs. Capcom Infinite there was a lot of doubt regarding the franchise ever returning in some sort of fashion..."
Capcom seriously dropped the ball with MvC Infinite. You can tell that it was heavily influenced by outside marketing that wanted to promote the characters in the MCU films only. The roster was lacking, the gameplay was slower than the previous game and there just wasn't a lot of the wackiness we come to expect.
From Xfire: "A lot of video games are designed to make players feel like a superhero. However, very few actually feature superheroes or have players take on the role of a superhero. What makes this even worse is that there are even fewer superhero video games that can be considered good."
