No unmarked spoilers please.
I just got this game today and I'm loving it! X4-X7 have all been various degrees of disapointing, but this game is great, I love the double teams, the tag teams, the assists, multiple weapons, items, the good cut scenes, and no men sounding like girls.
The best part is I got it at Best Buy for only $20, when it's $40 everywhere else.
GO GET THIS GAME FOOLS!
