I was walking through one of the underwater areas in fallout 4 while wearing my power armor. Codsworth was trailing behind me on the ocean floor about 10 feet behind me. Suddenly my controller started shaking and I heard something swim behind me incredibly fast. To top things off it scared Codsworth and caused him to say something about "did you see that!?!?" Unfortunately I did not see the creature but i did make a recording of the occurrence to try and see if I missed something. Have any of you seen this creature? Do you know what it is?

Never heard of sea creatures in the sea in boston, do you mind sharing what you saw/heard sounds like a take on the loch ness monster or could it be the mystery creature killing the dolphins across boston?

That's what I was wondering. I will try to figure out a way to post the video that I took to see if anyone else can pick up on what it was. I'm at work right now so I don't have access to my xbox at the moment.

It could've been something from the cancelled underwater quest, lore-wise it's entirely believable that some fish turned into mutants or sea monsters.

Fantastic. I am looking forward to this video.

If any of you are familiar with how to get a video from an xbox one onto this forum, I would greatly appreciate your help. I should be able to upload it by tonight if I get some tips on how to do so.

I dont think you can post any link here, yet. Only after more posts.

Upload to youtube and send me a private message with the link. I post here for you.
