carries the entire arsenal but only uses two weapons
One thing I really have to hand to the Doom 2016 gameplay loop: you can tell they really worked hard to make sure you couldn't do this. At multiple points you're basically required to use every single weapon just because it's the only way you actually have enough bullets to do it.
I'm a pretty big fan of the PS5 controller personally. Plays well with steam. Most games natively support button prompts for it also and for those which don't there are mods.
This might not be the case at this point as I'm mostly focused on fighting games, but for most of my life the general rule has been that officially produced first part controllers are going to be the best bang for your buck you can get as far as gamepads. You can get 3rd party controllers of equal or greater quality but very few if any at that level of quality at a competitive price point. Most 3rd party controllers marked at the price of an official controller or cheaper almost always use inferior parts and won't provide the same feedback or longevity. Unless you want to shell out for a premium custom build a current gen Xbox or Playstation controller is still likely the best option.
