I have over 200 hours on this game, all because i can't put it down. the best part about it is the fact that it is compatible with 3DS. me and my friend make the best team, and just when you think you've beaten the game, more missions pop up. that is why i love this game. it is almost never ending. once you beat low rank, you go on to high rank, and then G rank which goes on for just about forever. the highest rank of G rank i've seen is 245, but it goes higher. the game will never get finished, and that is why it is the best for the wii U
the style of play is a little bit to get used to, especially with the controls. but with plenty of options for armor and weapons, this game keeps you striving for better and better. I've sunk hundreds of hours into this game online. best online game on wii u. for now.
