Just a quick heads-up: Polterguys: Possession Party works well on Steam Deck! We've tested it internally and had no issues — performance is solid, controls feel good, and nothing breaks.
We also made a native Linux build especially for Steam Deck, so the game runs at maximum performance without relying on Proton or Windows compatibility layers.
We’re still waiting on the official Steam Deck Verified checkmark, but in the meantime, if you’re playing on Deck and spot anything weird, let us know. That feedback helps.
Thanks for playing,
The Polterguys Team
