By default, cross network matchmaking is enabled when playing Party Animals on Xbox One, Xbox One S, Xbox One X, Xbox Series S and Xbox Series X. This will allow you to play the multiplayer game with PC players.
If you think that some of the PC players have an unfair advantage, or outright cheating, then you can check out this guide to see how you can disable crossplay on your Xbox.
1. There is no in-game option in Party Animals where you can turn off crossplay. Instead, you need to head over to the Settings menu of your Xbox console.
2. From Settings, go to Account > Prviacy & online safety > Xbox privacy > View details & customize > Communication & multiplayer.
3. From the Account – Communication & multiplayer menu, you should see the “You can join cross-network play” column. Select the drop-down menu underneath it and then select the Block option.
4. Restart Party Animals to disable crossplay. If you have the game on Quick Resume, you need to manually quit out of the game and then launch it again in order to restart.
5. You should see the following message in the main menu when cross platform play is disabled:
Crossplay is turned off. This will make matchmaking slower and limit the amount of custom lobbies you can join. To change, please go to Xbox privacy settings.
You should now only be matched up with other Xbox players when playing the online multiplayer.
