How do you prefer to do it? I find the weapon wheels to be way too clunky especially when playing games like Doom Eternal.
I’ve been using the back buttons. Regular press for 1 2 3 4 and long press 225ms for 5 6 7 8. For some games a button chord for 9 and 10 but that’s rarely needed.
225 ms delay seems like a sweet spot. It’s short enough to switch guns quickly but long enough to make it different from a regular press.
I think it would be even better to have a proper numpad on the back of the steam deck but that would require some modifications. I think having 6 small back buttons per side is manageable and would greatly enhance FPS games.
I was fine with Doom Eternal’s weapon wheel, since it slowed down time it gave me time to pick what I needed. If you’re wanting to do quick weapon swapping like some high level players do that obviously won’t cut it though. That said, I had the back buttons already mapped to dash/jump/chainsaw/etc so couldn’t use them for weapons.
One way you could set it up is with control overlays, where you have one button cycle through multiple weapons. So you could have a back button that switches to super shotgun, but with a second press switches to the regular shotgun. Repeat that for the other weapon types with the other back buttons.
