Something’s going to be announced in less than 24 hours, and most Fallout fans will tell you that something will be Fallout 4.

Bethesda just tweeted this.

That please stand by image is iconic with the Fallout series. The link goes to a site with the URL fallout.bethsoft.com. Convinced yet?

If you hit the page source for that teaser site, there’s a message in the HTML. Here’s that.

PA system failure has occured [sic].

Shutdown of the Masterbrain has been authorized and all sensitive materials have been removed for security purposes.

Please attempt re-access. Have a pleasant day.

That teaser site has a countdown set to expire less than 24 hours from the time of publishing this post.

Stay tuned.
