This is a short clip of me playing Xonotic on a Steam Deck using joysticks + gyroscope to control my character. Xonotic is a FOSS game (it runs on an engine that is actually a direct descendant of the quake engine interestingly) in the genre of arena shooters which are typically considered impossible to play with anything but a mouse and keyboard. When console shooters gained prominence with halo, COD etc... it effectively shutdown a huge number of shooter fans from experiencing how much fun shooters can be that feature quake/arena shooter style movement. You can't functionally play a quake multiplayer style game with joysticks, even with intense autoaim it just doesn't work well. The thing is, and this feels so unexpected I can't help but find it hilarious, with gyro you CAN play a quake multiplayer style game with joysticks + gyro and it actually feels amazing. I am not amazing at Xonotic, but I know how to play (the bots are HARD lol) and with gyro helping with fine aim control I can play very competitively (for how good I am). Oh my, using gyro to steer devastator rockets might just be the most fun I have ever had with a rocket launcher... My steam controller mapping for Xonotic is: Gyro set to always on (set it to toggle on and off with dpad if you want), The 4 rear buttons, 2 bumpers and 2 joystick clicks are mapped to the various Xonotic weapons (number keys). Arguably superior to toggling weapons on a keyboard once you have muscle memory?, Left joystick is mapped to a 8 Way (Overlap) directional pad with an Overlap Region setting of 4100. The Outer Command Radius is set to 29395 (might need to fiddle with this value for your particular steam deck), and the Outer Ring Command set to spacebar., That last setting is the real kicker, when you push the movement joystick (left joystick) to its full extent you automatically start strafe jumping which honestly makes strafe jumping feel more intuitive than using a keyboard and mouse. Keeping momentum through complex direction changes is also super easy since the joystick is basically already integrating that for you, you just pick a direction and push the joystick. The joysticks also don't need to be returned to center like a mouse must. To rotate large amounts with a mouse you have to constantly lift and reset the mouse when it reaches the edge of the mousepad. With a joystick you just hold the joystick... This makes chaining the kind of complex snap rotations that accelerate you in quake style movement mechanics easy and fluid feeling. You are also never caught with your aim centered on a target but your mouse all the way out at the edge of your mousepad in a poor position to track a target. Edit I don't think it needs to be said, but Xonotic could probably run on the computer chip in your refrigerator. My steam deck is stone cold when I run Xonotic on it, I bet Xonotic gets better battery life performance than 95% of 2d games... No issues running Xonotic on linux of course, I just searched for Xonotic in the "app store" of the Steamdeck Linux OS (in desktop mode) and installed it. Then I added it to steam as a non-steam game so I could setup steam controller mappings (I like steam's controller mapping UI but you could use something else).
