Meanwhile, The Old Blood includes Nazi zombies - but don't expect them to work exactly like you remember from the 2001 cult classic Return to Castle Wolfenstein.

"These types of enemies can be tricky, because they don't typically have range weapons," executive producer Jerk Gustafsson, of developer MachineGames, said in a post on the Bethesda Blog.

"But in The Old Blood, some of them actually use a rifle, and we also have some intense dash attacks!"

One question this throws up is: why not launch a physical edition of the Xbox One version?

When asked for comment, Bethesda told us the following:

"Availability at retail will vary by territory but currently, our plans only include physical versions for PC and PS4. Should anything change, we will let fans know."

Not much of an answer.

The Old Blood is a standalone prequel to Machine Games' Wolfenstein: The Order, and as such carries a budget £14.99 price (it's not yet up on the PlayStation Store but is on Steam, priced £14.99).

There's also the issue of why The Old Blood will skip a release on PS3 and Xbox 360, when The Order launched on those platforms.

"To achieve our intended scope for the game, we decided to focus on current gen," was Bethesda's explanation when asked for comment.
