Wolfenstein: Youngblood is a game that is intended for co-op play, with an A.I. controlled bot taking control of the other character when playing the single-player mode. One restriction of co-op play is that there is no split-screen mode on any version of the game, which means that the player will need to go online if they want to play with friends.
Wolfenstein: Youngblood follows the twin daughters of B.J. Blazkowicz, who must enter Nazi-occupied Paris in order to find their missing father. The twins need to seek out members of the French Resistance in order to cripple the Nazi regime, which involves shooting a lot of robots in the face.
The co-op part of Wolfenstein: Youngblood's gameplay is so important that there is a version of the game that exists to help bring people together to play it. The people who purchase the Deluxe Edition of Wolfenstein: Youngblood will be given access to the Buddy Pass. The Deluxe Edition costs $10 more than the base version of the game, so it would be a much better deal for people who only want to play the game with their friends.
Play Without Pay
The Buddy Pass allows the player to invite their friends to play Wolfenstein: Youngblood with them without needing to purchase the game. The other player can experience the entirety of Wolfenstein: Youngblood alongside you without ever having to pay a dime. The Buddy Pass also isn't restricted to a single person and multiple people can play through the game with the person who purchased it, though they can only do it one at a time.
In order to use the Buddy Pass, your friend will need to have a Bethesda.net account that is linked to the account of whatever system you will both be using to play the game. The other player will then need to download a smaller version of the game, which can only be played with the owner of the Deluxe Edition, who can invite them into a game that they are hosting.
A Few Rules
There are some restrictions to using the Buddy Pass, as the other player can only play with you as part of the co-op mode and they won't receive any achievements. All of the progress the other player makes in the game will be carried over if they upgrade and purchase the full version of Wolfenstein: Youngblood. The two players will also need to have purchased their respective online subscriptions (Nintendo Switch Online, PlayStation Plus, or Xbox Live Gold) in order to play the game online on consoles.
There is currently no crossplay options in Wolfenstein: Youngblood, which means that the Buddy Pass will only work for friends who possess the same system that you purchased the game on. The Buddy Pass is available for every version of the game, though it has yet to be confirmed to be part of the Google Stadia port, as few details about it are known as of the time of writing.
Wolfenstein: Youngblood is available now for Nintendo Switch, PC, PlayStation 4, and Xbox One. The game will be coming to Google Stadia in the future.
