The doctor is in! Mario takes a break from his adventuring ways and once again dons his stethoscope for a new generation of germ-battling mayhem. In addition to the classic mode of using vitamins to exterminate viruses, you'll find two battle modes and an online multiplayer mode where you can hone your skills against players from around the world. Feel like challenging a friend who doesn't have Dr. Mario Online Rx? Then the WiiWare-exclusive Friend Battle Demo is just what the doctor ordered. Or maybe you'd like some help taking on those nasty viruses? Try out Virus Buster, where four players can simultaneously move capsules simply by pointing at them with a Wii Remote controller. Any way you look at it, Dr. Mario Online Rx is a prescription for fun that everyone can enjoy.
