Jeff Gardiner, lead producer on Fallout 3 DLC, has spilled some scary beans on the weapons available in the upcoming Mothership Zeta.

He told MTV Multiplayer that, "Mothership Zeta is full of the most high tech weaponry in the game. It includes a Shock Baton for melee fighters, multiple new firearms including an Alien Atomizer, a pistol, and the Alien Disintegrator, a new rifle. There's also a new grenade type, a Cryo Grenade, which freezes enemies for a short period of time. On top of that there are new unique weapons, and a new heavy weapon."

Gardiner also revealed a new perk dubbed 'Xenotech Expert.' "It increases the damage you do with alien weapons, including the Alien Blaster if the player had found that in the wasteland", Gardiner explained.

Sounds like excellent news for Xbox 360 owners. It's slightly less good news for PS3 owners, given that they'll have to wait longer for it than they first expected.
