The House of the Dead: Overkill is a first-person rail shooter video game developed by Headstrong Games and published by Sega for the Wii. It is the fifth game developed in the The House of the Dead series, a prequel to the original House of the Dead chronologically and the first in the series to be released exclusively on a home console. It was released on February 10, 2009 in North America and February 13, 2009 in Europe. The game was released in Japan on September 17, 2009 bundled with the Wii Zapper accessory. The Japanese release, however, had to be drastically censored in order to still get the CERO-D rating.
