Steam Deck FAQ
What OS is Steam Deck running?
SteamOS 3.0, a new version of SteamOS based on Arch Linux.

Do I need to port my game to Linux to have it work on Steam Deck?
No porting necessary. Your Windows build will likely work right out of the box, thanks to Proton.

Any tips for making my game great on Steam Deck?
There are a few things you can do right now, without a developer kit, see those recommendations here.

Can the Steam Deck be docked?
Yes, the USB-C port can be expanded with a hub or a dock into HDMI and USB while still retaining power / charging pass through.

My game uses anti-cheat, which currently doesn’t work with Proton - how do I get around this for Steam Deck?
We’re working with BattlEye and EAC to get support for Proton ahead of launch.

Will people be able to install Windows, or other 3rd party content?
Yes. Steam Deck is a PC, and players will be able to install whatever they like, including other OSes.

When can I get a developer kit?
