According to Nintendo, the first Super Smash Bros. for Wii includes more moves, more levels, online battles, Nintendo Wi-Fi Connection, a variety of control options, a host of playable characters, and even an adventure mode that's a full game in itself.
Choose from a number of iconic and new characters including Mario, Meta Knight from Kirby, Pit from Kid Icarus, Zero Suit Samus from the Metroid series, Sega's Sonic the Hedgehog, and even Konami's Solid Snake.
Customise your Super Smash Bros. Brawl experience as you select your favourite Nintendo music to brawl to, and choose the control scheme that suits you best. Control options include the Wii Remote alone, Wii Remote with Nunchuk, Classic Controller or Nintendo GameCube controller. And with the the Nintendo Wi-Fi Connection, users can brawl with friends or strangers, share photos, swap replays, team up for challenging mini-games, and send custom made stages or screenshots to friends.
The adventure mode ‘The Subspace Emissary' is a new mode for brawlers where you fight your way through enemy packed side-scrolling levels. Meet up with other characters, take on bosses, or even play two player cooperative. In this mode the world of Smash Bros. is invaded by the Ancient Minister and his army of creatures. The Ancient Minister is turning characters into trophies to harness their power, and eventually all the characters must work together to defeat the invading creatures.
