Yes. Github.com

I haven't compiled it for Linux so it won't just work out of the box. I haven't used Linux much at all but maybe Wine or Proton can make it work.

I know for a fact that several of the Halloween Horror maps have disabled certain elements like the HUD and the flashlight for a more immersive experience. For example, The Sun Vanished disables the HUD, flashlight, crosshairs and slows the player down. Shadow Walker 2 doesn't disable anything, I recommend you loading up that map and see if you actually have issues with things being disabled when they aren't meant to be.

Holy crap that was unexpected

The csgo branch isn't anymore laggy than any other branch.
