Players move the UFO with the analog stick of the Nunchuk, and then use the pointer function of the Wii Remote to direct a swarm of up to 100 invaders in blowing up buildings and destroying the defending forces of Earth, with continuing destruction increasing the time available to the player.

[8] The final battle of the game is against the original UFO that crashed on Earth 30 years ago during the first invasion, upgraded and modified by the earthlings.

Wired's Chris Kohler found the gameplay in the Starter Pack to be "addictive and well-balanced", yet lamented that making the rest of the stages available only as paid downloadable content was like "the modern-day equivalent of Insert Coin To Continue".

[11] These sentiments were also echoed by 1UP.com, who gave the game a B− grade and called the gameplay a "high concentration of amusing (and plain ol' fun)" action.

[12] IGN gave it a 5.9/10, praising the gameplay and the game's humor, but could not justify the cost of purchasing the whole package.
