The Nintendo Wii's gaming inventory is rather sparse when it comes to edgy, foul mouthed, shooters built to appease a mature audience. Curiously enough, SEGA has filled that void in an unprecedented way with a surprising entry titled 'The House of the Dead: Overkill".Resembling a classic shooter from the days of rampant arcade gaming, Overkill is an on-rails shooter that leads the gamer through various environments filled with hordes of blood thirsty zombies and demonic boss battles. Because of the nature of an on-rails game, the premise is simple: using the Wii controller, the gamer aims and shoots oncoming predators while the camera pans about in a predetermined manner.Because the Wii is anything but performance savvy, there are times when the frame rate becomes rather choppy; however, the game is stable for the most part and, oddly, video anomalies only seem apropos for a title that thrives on the nostalgic grindhouse panache.Of course, we couldn't simply call Overkill a take on the grindhouse theme without a cheesy script, some third-rate acting, and an over-the-top storyline. Fear not - Overkill features all of the above!From the game's opening sequence to its deranged conclusion, SEGA leaves no opportunity overlooked in its quest to create a cringe-inducing blood bath, reminiscent of the film genre it imitates. The quips are blatantly profane, the plot is about as rediculous as it can get, and there is no shortage of gory moments and animated pornography, to boot. It doesn't stop here.What grindhouse flick is complete without an equally ludacris soundtrack? Overkill satisfies this inherent need with a playlist which sports lyrics that will either make you chuckle in hilarity or blush like a prude.Make no mistake, this isn't just a zombie-killing survival game. Overkill is the real deal when it comes to all-out absurdity and makes no apologies for it. The gameplay is addictively simple (though the difficulty can be quite challenging), the presentation is pitch perfect for what the developer aimed to achieve, and the game provides for mindless fun when loading up another round of Mario just won't suffice.The level design is a collection of nighmarish environments, nicely put together to stir up a sense of uncertainty and danger, including a house infested with the undead and an amustment park, complete with flesh-craving clowns. Truth is: if you have witnessed it on film, odds are SEGA has re-envisioned it in the Overkill ... gore and all.If the 'M' rating wasn't evidence enough, parents should carefully consider this purchase if intended for a younger audience. There is a lot here that will, in most cases, be offensive. For the mature crowd who welcomes the aforementioned craziness, The House of the Dead: Overkill is a hidden gem on a platform teeming with family friendly titles. If you are the latter, I highly encourage the item. Couple it with the Nyko Perfect Shot, a dark night, and you have hours of fun awaiting you!
