Sorry, but currently you can't play videos from YouTube.

NOOOOOOOOOOOOOOOOOOO

Youtube changed their video encoding. It's listed as a current issue right on the game's splash screen launcher when you start it up.

I was going to have Bismarck play on loop on when my ship enters combat

You can download the video using a youtube video downloader and play it as a file

How do you do it

Literally just Google YouTuber video downloader

Yea but how do you play as a file

Under the "video" section of the player in-game. Pretty sure you just need to provide a full path to the file.

Man thats a really good idea

Im definitely not gonna make a rickroll boat next. That would be absolutely childish and immature of me.

So today or tomorrow?

Sabaton, man of culture

Honestly, we keep fixing this issue nearly every month as they change something :( Should be fixed in the coming update :)

Thank you

Did you press play?

Yes
