Fallout 3's DLC producer, Jeff Gardiner, has said that Mothership Zeta will have "the most powerful weaponry in the game."
Mothership Zeta will be the fifth DLC episode for Fallout 3, following on from this month's Point Lookout DLC release for Bethesda's RPG.
"The player will have a handful of tasty alien technologies to play with," explains Gardiner. "There are new fire arms and melee weapons, which will comprise the most powerful weaponry in the game."
