So far the House of the Dead 2 & 3 Returns is basically a package of the respective Dreamcast and Xbox games with nothing new. However, Sega is adding something for Wii owners and it has something to do with motion control. House of the Dead III has Extreme mode, which includes a guard attack command. When zombies are piling on top of the screen you can shake the remote to knock them back. As of now, House of the Dead II doesn’t have any new modes, but the item collecting “original” mode (umm..) returns.
