Valve lists this game as unsupported for Steam Deck, but I think the Playable rating would be more accurate.

Once you start up the game, you'll be greeted by a launcher window. The only settings you need to change are the input device (from Keyboard to Xbox 360 controller), and the resolution (from 800x600 to 1280x800, the Deck's native resolution). High Detail can stay enabled.

After that, the game performs flawlessly. The game is programmed run at 30FPS and maintains that frame rate perfectly, and the default controls work without a hitch.

For those that want to, you can go into Steam Input to set the left trackpad to Joystick (not "As Joystick ", just "Joystick "). This way you can control the Force Grip through the left and right trackpads, since the right trackpad already emulates the right joystick by default. I would recommend playing around with the trackpad sensitivity settings to your liking, or I've also submitted a community layout with my personal Steam Deck setup for others to try.
