Picked this up due to it being discounted on the Xbox store, I had previously dismissed it due to the art style being not my taste. It's surprisingly solid. The heavy-handed comic book atmosphere isn't my thing at all but the actual fight mechanics and minute-by-minute gameplay are very well done.
It plays like SoR4 but with a toned-down combo mechanic and the ability for all characters to run/hop. The melee weapons and guns are handled in a way where I actually wanted to use them. Crowd clearing specials have their own meter (rather than costing life). It also has a block button (ugh) but it's implemented in a way that can be a viable strategy and not just a waste.
It's worth checking out, although maybe not at full price depending on how much you like the genre. It's not as good as SoR4 or Shredder's Revenge, but far better than Final Vendetta or The Takeover.
