The M-rated grindhouse film-inspired gore fest House of the Dead: Overkill has managed to make a modest bit of headway on the typically family-friendly Wii.

The light gun game from Sega and U.K.-based Headstrong Games sold 45K units during the month of February, NPD told Edge. The game launched February 10.

NPD analyst Anita Frazier said it landed around the 50th spot in the top-100 SKUs for the month in unit sales.

Sega's lineup of M-rated Wii games includes House of the Dead: Overkill, Platinum Games' MadWorld (launched in March) and June's The Conduit, from High Voltage Software.

Sega of America has said that developers are missing an opportunity to cater to the hardcore gamers that have bought Wii, a console that Nintendo positions as typically family-friendly.

House of the Dead: Overkill recently earned a rather dubious honor from Guinness World Records as the "Most Profane Game."

From Edge

 VGChartz has it at 52,003 in February.

45K US from NPD
52K NA from VGC.

Seems about right.

It'll have legs.

So Madworld is set to beat the snot out of it, as it did roughly that number first week.

wow spot on, nice!

not rlly, thats almost 15 % off

NPD doesn't include canada.

Sorry but I don't trust VGC numbers.

 That doesnt change the fact that they were pretty darn close with this game depending on how good sales were in canada. Is canada the only other country VGchartz tracks in the NA category. What about mexico, and all the other countries?

if VGC can't get USA right, what makes you think they get mexico and canada. 15 % off is not darn close.
