As many of you know probably already know Metal Slug Anthology will support the GameCube controller aswell as the Wii remote.
Some recent game footage over at gamevideos.com has shown of the many quirky ways the Wii mote is used in the game.
Nunchuk - General movement and fire, with a flick of the Nunchuk tossing grenades.
Wii Remote - If no Nunchuk is attached the Wii mote can be titled for movement along with the D-Pad 'up' button for jumping.
Arcade Style - The Wiimote is held vertically against a playing surface (Joystick) and the Nunchuk attachment fires and jumps (flick for grenades)hold Wiimote vertical against surface (emulates joystick)
Nunchuk Only Option - Nunchuk controls all (except weapon switch and alternate attack)
Seems a bit overkill to me, are so many controller options really necessary?
