eXtinction offers gamers an action-packed arcade experience. Players advance through 30 levels and defeat six savage bosses as special agent Nick Naster, a space pilot who has had top training in a multitude of modern weaponry. Naster loses his family to an alien virus known as Zeta 2, which mutates humans, and thus volunteers for the eXtinction mission. He must now wipe out all vestiges of the plague with the help of nine weapons including a chaingun, magma cannon, missile launcher and photon thrower.
