Bethesda Game Studios put up a Fallout teaser website yesterday. The countdown on that site ran down to 00:00:00 today, revealing — surprise, surprise — a trailer for Fallout 4:

Also, the faux-legalese on the website is pretty amusing:

The act of using this Web-Site (either partially or in its entirety) is a binding, non-verbal agreement between all Vault-Dwelling Parties (either Fully Resident or Temporary), Interested Vault-Dwelling Parties, and Vault-Tec Industries stating that Vault-Tec is not liable for any damages, injuries, or mental anguish inflicted during or after the perusal of the Vault Dweller’s Web-Site either in its Full Desk-Top or Condensed Pocket format. Use of this Web-Site without sufficient understanding of Science may result in death. Always consult your Vault Overseer for guidance on appropriate Web-Site usage.

The game has been confirmed for PC, Xbox One, and PlayStation 4; it would appear that Bethesda have no plans to support previous-generation consoles. Presumably we’ll get more of a look at the game at E3, although the trailer does at least show enough to confirm that the game will be set (as I believe has been speculated previously) in Boston.
