Instructions
Use the Wii nunchuk's analog stick to move Ben 10. Press the "C" button on the nunchuk to block and the "Z" button to jump.
Press "Up" on the Wii remote's directional pad to activate the Omnitrix. Alternatively, hold the "C" button on the nunchuk and move the Wii remote toward your wrist. Press "Left" or "Right" on the directional pad to choose an alien form. Press "A" on the Wii remote, with the Omnitrix activated, to select that form.
Press "A" for a light attack. Alternatively, shake the Wii remote back and forth to perform this attack. A light attack is a quick attack that does not deal much damage.
Press the "B" button on the underside of the Wii remote to activate the heavy attack. Alternatively, shake Wii remote front to back to also activate this attack. The heavy attack does a lot of damage but is slow to activate, leaving you vulnerable to damage from other enemies.
Press "Down" on the directional pad to perform a special attack, or move the Wii nunchuk side to side rapidly. The special move performed is based on the alien form you have selected.
Press the "Plus" button on the Wii remote to pause the game. Press the "Plus" button again to resume the game.
