If Mario, Princess Peach and the rest of Nintendo's chirpy, family-friendly characters got a glimpse of the Wii blast-em-up game House of the Dead: Overkill, they'd probably be committed to a Mushroom Kingdom mental institution.
Overkill is one of the rare adult-oriented games for Nintendo's wee white console; hell, it actually begins with a scantily clad stripper writhing and licking a Wii Remote like a sex toy. From start to finish it's an unapologetic ride of guns, gore and other grotesquitudes, not to mention an entire Scorsese movie's worth of f-bombs in just about every possible linguistic permutation.
Pokemon this ain't. And that's not such a bad thing.
