The popular on-rails arcade shooter has been announced by SEGA for the Wii. It will essentially be a port of the arcade game, but with 4-player multiplayer, new items/stages, and even online capabilities. For anyone who’s never played the game before, it’s essentially your basic on-rails shooter in which you shoot the badguys that pop onto the screen, try not to hit the incredibly annoying civilians, and take out the occasional helicopter or two.
