I'll be up for online play in probably 1-2 weeks after my exams.
So far, I enjoy some rounds of singleplayer in my breaks. What a cool game this is, I really enjoy trying different characters in missions that allow it and the system seems to be easy to learn but hard to master (e.g. other combos when you time your punches differently, some tactical thought going into when to make killer weapon attacks or go into rampage mode). Some of the characters could have been fleshed out more storywise and don't have much screentime, but all seem fleshed out gameplay-wise so far.
Really, a cool game
wouldn't even compare it to MadWorld too much apart from being a similiar genre and featuring some of the same characters. Pacing seems much faster, the fighting system is more fun to me without the "kill spectaculary for highscore"-thing. I enjoy the style of the game very much, great use of color, contrast and subtle animations to give every character his own flair. No need to talk about the OST - it's awesome and very fitting.
On the negative side, I still miss the 2 player splitscreen option, though :/ would have been great to play this with friends at home against bots, I'm usually not that big into online play but I will probably dig into this just for the sake of it ^^ Also, while I love the existing scenarios, I would kinda like to have 1-2 more of them, especially since some interesting scrapped concepts are hinted at in the art gallery... but that's just me being greedy.
