Kongi the Conqueror's Pancake FPS Starter Kit for Source 2 games is not primarily intended for playing Half-Life: Alyx, as the modder is at pains to explain. «Please don't use this to play Half-Life: Alyx and then complain about the game being bad!!!» as the GitHub pages puts it. «This was NOT intended to be used to play Half-Life: Alyx with!!! It is intended to be a base for non-VR supporting addons for the Source 2 Engine to use!!!»But guess what? People have been using it to play Half-Life: Alyx, including YouTuber Goutrial, who combined it with several other mods for what seems like the ultimate non-VR Alyx experience. The Half-Life 2: MMod Team came up with a bunch of weapon sounds and animations, Jun Choi over on ArtStation modeled the weapons themselves, and then Shadow_Run on GameBanana combined those animations with those weapon models. Jeremy Lorelli on GitHub provided the Vscripts, and when you add those things together what you get is a version of Half-Life: Alyx with first-person arms holding guns that you can shoot with your mouse.
