Experience an alien invasion - from the perspective of the attackers! In this action-adventure you take on the role of Cryptosporidium 137 and terrorize humanity to collect their DNA.
In 1969, ten years after Destroy All Humans!, Cryptosporidium 137, is deceased for reasons unknown, and his clone, Cryptosporidium 138, made of more complete Furon DNA, is now taking his place and continuing to pose as the United States President. KGB intelligence reveals early on that Crypto 138 is the first and only Furon to have genitalia since the Martian War, which is referred to only as "The Package".
Big Willy Unleashed takes place before the events of Path of the Furon and after Destroy All Humans! 2. The game is set in 1975, 6 years after Destroy All Humans! 2. Cryptosporidium 138 and his mentor, Orthopox 13, attempt to support the popularity of Big Willy, a fast food restaurant Orthopox owns.
After Destroy All Humans! Big Willy Unleashed, Crypto 138 has resigned his Presidency and Natalya has died because of her clone having only a four year life span, has crashed his old saucer into a casino's electronic ticker display while drunk, and was killed in the crash.
