Who you gonna call (a Wii port)? Ghost Squad!
Sega just announced plans to port their arcade light-gun shooter,
Ghost Squad, to the Wii -- falling into lockstep with other publishers, like
Capcom, eager to dip their toes into Nintendo's swimming pool of cash. Sega isn't just doing a straight-up port of their on-rails shooter though;
Ghost Squad for Wii includes the requisite Arcade mode in addition to a Multiplayer mode with support for four players (
take that arcade cabinets of yore!).
