Destroy All Humans - Greatest Hits is an action-adventure video game for Sony PS2 Playstation 2, developed by Pandemic Studios. In this sci-fi classic, players assume the role of Cryptosporidium-137 (aka, Crypto), an invading alien on a mission to harvest human DNA and bring down the U.S. government. With an array of hi-tech alien weapons at disposal, the player schemes through strategic tactics and hilariously chaotic action to obliterate hapless humans. The game also features free-roaming and sandbox gameplay, allowing exploration of 1950s America in an illustrated, sci-fi style.
