Mothership Zeta

Mothership Zeta will be the fifth and last Fallout 3 add-on, to be released on August 3, 2009 for the Xbox Live and Games for Windows Live. The PlayStation 3 version is to be released after Point Lookout.

The add-on will cost 800 Microsoft points or $9.99. It won't be part of any of the Fallout 3 Game Add-on Packs, and the only disc release it will be available with is Fallout 3 Game of the Year edition.

Overview
In Mothership Zeta the aliens have returned and they are not happy. The mothership answers the distress call sent out by the alien ship at the Alien Crash Site and abducts the player, making the whole add-on take place onboard of the alien ship. Mothership Zeta is in orbit around Earth and the aliens have been watching Earth for quite some time.

You will recieve an unintelligable radio transmission which will lead you to the Alien Crash Site which players might already have visisted. It won't be the friendliest of greetings. The player will then be abducted and will end up on the alien mothership, Mothership Zeta, where they will meet other prisoners and plot their escape. The other prisoners originate both from the Capital Wasteland and from Earth’s past.

Onboard the Mothership, the questline won't be completely linear and will feature some exploration. You will be able to take a spacewalk. There will be Alien Power Cells but still in a limited quantity

The environment will be artistically different from the rest of Fallout 3, with nearly no assets reused.

Story
When asked about the storyline of Mothership Zeta, Jeff Gardiner revealed; "The general plot starts out as an escape attempt until the player figures out what the Aliens are actually up to. There are a number of other abductees for the player to interact with, and from whom they can solicit help."
