By most accounts, Wolfenstein: The New Order was a roaring success. And quite an unexpected one, too. It has been more than half a year since the latest iteration in the long-running Wolfenstein franchise was released, but Bethesda Swedish developer MachineGames aren't quite done with it just yet.

The Old Blood, a "daring plan to infiltrate Castle Wolfenstein", is a stand-alone prequel to The New Order, set to release on May 5th, costing £14,99 or your regional equivalent. It's not quite certain what it'll offer specifically, but the trailer embedded above teases new weapons, enemies and secrets. That is, of course, in addition to the brand new campaign that'll lead up to the events taking place in The New Order.

"The year is 1946 and the Nazis are on the brink of winning World War II. In an effort to turn the tide in the Allies' favour, B.J. Blazkowicz must embark on an epic, two-part mission deep within Bavaria. Part one of Wolfenstein: The Old Blood - Rudi Jäger and the Den of Wolves - pits BJ Blazkowicz against a maniacal prison warden as he breaks into Castle Wolfenstein in an attempt to steal the coordinates to General Deathshead's compound. In part two – The Dark Secrets of Helga Von Schabbs – our hero's search for the coordinates leads him to the city of Wulfburg where an obsessed Nazi archaeologist is exhuming mysterious artefacts that threaten to unleash a dark and ancient power."

Well, that just sounds like some genuine old-school fun in a violent package. A couple of livestreams are set to be shown during PAX East this weekend on Twitch, but in case you miss it, we'll let you know if anything interesting comes out of that. If not, you can likely expect a review from us in May.
