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].

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

Stay tuned.
