First it was just going to be Karous, then Milestone decided to toss Radio Allergy/Radilgy and Chaos Field on the disc. Now the package is officially called Milestone Shooting Collection Karous Wii, and it's being released in Japan on March 27th.
Karous has been enhanced with some slight waggle: you can now swing the Wiimote in order to swing the sword weapon. It sounds kind of distracting to have the controller waving around while you're trying to make precise movements. We would like Classic Controller/Hori stick play with this title, so we hope that the waggle is optional (and that the game supports the Classic).
Radilgy and Chaos Field seem to have been left untouched from their Gamecube iterations. Not that we mind -- the only difference we want to see in Radilgy is in the crucial "being released in the U.S." category.
