The Wii has made home versions of light-gun games possible. Some of the first games in this style to be released for the Wii were ports of arcade games. Several of the House of the Dead titles were packaged together and released previously, but there was also a completely new title in development.
It’s called House of The Dead: Overkill and it combines all the best features of a light-gun game with all the best/worst features of campy horror movies. It’s directly aimed at the semi-casual market, with the content definitely not for kids and the gameplay on the relatively easy side.
The controls are incredibly simple, but for this style of gaming it’s exactly as they should be. Point, pull the trigger on your zapper or other lightgun accessory (or simply push the B button) and shoot. Shake to reload, shoot again. If you’re just going through the game you can simply blast away; enough hits will take down any of the walking dead. Hits to the limbs will sever that body part and of course headshots will take them down immediately.
