I loved the aliens in Fallout 3. Mother Ship Zeta was a blast! Are aliens returning in Fallout 4?

No, Todd said they were one of his most regrettable additions to Fallout 3.. Or atleast I think he said it in my dreams..

He said that in your dreams too??

MZ svcked lol I'm assuming Beth doesn't even consider that canon?

Ignore death toaster. Spoiler alert: there are aliens in the game, how common they are I do not know but I watched a stream where the player fought aliens and had one of their weapons.

If you ask for a spoiler, please ask in the spoiler section where I am moving this. Please and thank you.

Just play the game, one loading screen will give you that answer really soon

Aliens are in, at least in one event. https://www.youtube.com/watch?v=qOIq03sCBHM
