Wolfenstein: Youngblood is the first CO-OP focused game in the series, but thankfully, there is an offline single player mode for the less social of us to enjoy as well.
The Wolfenstein: Youngblood offline single player mode works much as you'd expect, with a few caveats to keep in mind. For example, you still get a partner to play with, but her AI is infamously bad. Find out how it works - below.
Wolfenstein: Youngblood Offline Single Player
While technically still an "online" match, in that the game creates a private server instance, Wolfenstein: Youngblood's solo mode does function normally. First go to 'New Game' and pick your character, then you'll have to pick 'Nobody (Offline) to actually start your solo match. If you choose 'Friends Only (Online), you'll start your match solo, but your buddies may join if they wish.
From our experience, though, Youngblood is definitely best played in CO-OP. Even if you don't have a friend who also owns the game, you can invite them to play with you via the game's Buddy Pass, which is a lovely addition to the mix.
Having released just yesterday, Wolfenstein: Youngblood is now in the limelight. Stay tuned for more useful info on the game as we figure it out.
