The sci-fi action franchise's debut on a Nintendo platform features four unique open-world environments to explore and high fidelity destruction on the ground, in the air via UFO and in the all-new Big Willy, a prototype alien mech masquerading as a fast food restaurant mascot. Developed by THQ's Locomotive Games, Inc., Destroy All Humans! Big Willy Unleashed is now available for the suggested retail price of $49.99.

"The Destroy All Humans! franchise turns the tables on traditional sci-fi gaming, allowing gamers to play as the alien and unleash massive destruction," said Brad Carraway, director, global brand management, THQ. "Big Willy Unleashed continues this tradition and brings the franchise to Wii gamers for the first time, with new features like the Big Willy mech that really ramp up the game's destructive mayhem."

"Big Willy Unleashed was designed for the Wii from the ground up, providing a unique Destroy All Humans! experience gamers won't find anywhere else," said Jack Sorenson, executive vice president of worldwide studios, THQ. "The game offers three different modes of play, with Crypto, his UFO and his Big Willy mech, creating a variety of ways to unleash high-fidelity destruction."
