Bethesda have released three new screens from the fifth (and final?) downloadable episodes for Fallout 3 - Mothership Zeta. In this expansion players will find themselves abducted by the returning aliens, but that has its perks - in the shape of fancy alien weapons and a new perk.
The new weapons include a Shock Baton, Alien Atomizer (pistol) and the Alien Disintegrator (rifle). On top of that there will be new unique weapons, a new heavy weapon and a grenade called Cryo Grenade that freezes enemies. The new perk "Xenotech Expert" increases the damage you cause while using alien weaponry.
Mothership Zeta will take off on August 3 on PC and Xbox 360, with the PS3 version arriving sometime this fall.
