Whether you pronounce it Mothership Zeta or Mothership Zed-eta, the fact remains that the aliens are coming to cause some trouble in Fallout 3's Capital Wasteland very soon. Beyond a trailer of what to expect when Mars (Jupiter, Uranus?) attacks, there is also a developer's diary on the little details of the DLC's creation. Mothership Zeta will be ready to abduct our wanderer and our wallets on August 3 for 800 ($10) on PC and Xbox. The PlayStation 3 version will be available at a later date, and we'll let you know when the little grayish-green men inform us of that abduction date.
