Wolfenstein Youngblood made a lot of changes to the Wolfenstein series, and while some of it is still familiar, there are so many new elements. A lot of players have been confused as to how exactly they save the game in Wolfenstein Youngblood, so here's how it is done.
To save your game in Wolfenstein Youngblood, do any objective to trigger the auto save feature. There is no way to manually save the game, so you have to rely 100 % on the autosaves. These are saving fairly often though, so it's unlikely that you will lose a lot of progress if you shut down the game.
In order to trigger an auto save, complete any objective in the main quest line, or in any side quests. When this happens, you will see a cassette animation which symbolizes the autosave.
The only exception is when you are currently on a side mission and die. If that happens, you will be reloaded to the beginning of the quest instead of the previous autosave point. So it might be worth restarting your console or game if you die very far into a side quest.
And that's everything there is to know about saving your game in Wolfenstein Youngblood. It's a bit of a hassle to not have access to manual save files, but the game saves so regularly that it's not really a problem at all.
