EuroGamer have taken a look at the PAL version of Luigi's Mansion, the GameCube's flagship launch title. Here's a snippet -
"The game is a bold departure from previous Mario Brothers titles. Unlike his bouncy brother, Luigi doesn't jump, bop people on the head or throw fireballs. He doesn't fly, and he doesn't collect stars. Well, only once. Luigi's spooky adversaries are almost infallible, susceptible to nothing but the quirky Prof's modified vacuum cleaner, the Poltergust 3000. Using the pressure-sensitive left and right shoulder buttons to blow and suck at the desired rate, Luigi can gobble up ghosties and bag the Boos, before returning to the Prof's lab to turn them into portraits for the gallery."
