I really hope this question isn’t just a stupid one, but I ordered the new 1TB deck and a docking station then thought, how would I play it docked? Is there a secondary controller I would need to order? Or am I casting the game to the screen and I just use the deck? But then it wouldn’t be docked lol…
I use Xbox Series controllers over Bluetooth.
The Steam Deck is ‘just a PC’ and just like any PC, you can pair a wide range of controllers to the device. Heck, I use an infrared remote on my Deck when docked to control Kodi for media. :P
