It will have to do with the armor or a drug I bet...because the costumes are different as well, and it will be explained.
Even still, I look at the action and it is too over the top. I love multiple stage levels but instead of a simple stage transition they make a longish cinematic that takes me out of the fight, and realistically would kill almost all those heroes and villains.
It is too exaggerated, and that style works well for Mortal Kombat, it shouldn't be anywhere near the DC property. I think that is what frustrates me most. It is that Warner Brothers is allowing a company that made a good fighting game just remake that same style of fighting game with a property that doesn't fit.
When Capcom made the Marvel games, they did not make a perfect Street Fighter clone with marvel characters. They exaggerated the action, but kept it light and colorful and very cartoony and comic friendly. It fits the characters and is fun. Nothing about this Injustice feels fun. It fills too gritty for the characters and when almost all the special moves would actually be kill moves in other games it feels sloppy.
And I really, really hate the supers. Some of them look really cool, but in the end, take me completely out of the play experience. Just like I am not a fan of Street Fighter 4s Super moves for the same reason. I want my Super moves to be seemless with the game, but cinematics.
