Skipper Hi,
Currently, you can use the controller to press the "LB"+"RB" button in the custom room to create a new local player, supporting up to four players for split-screen gaming on PC.
Local multiplayer requires multiple controllers, such as two players needing at least one keyboard and one controller.
Due to hardware limitations, Xbox One consoles only allow a maximum of two local players to play simultaneously.
We have received your suggestion and will forward it to the relevant team for consideration.
Thank you for your support of Party Animals!
Best,
Party Animals Support Team
