I've been waiting for this one! Dr. Beef has previously ported Half Life (Lambda1VR), Quake (QuakeQuest), and Quake 2 (Quake2Quest) to Quest, and has now released QuestZDoom, a port of the GZDoom engine which supports many of the most popular Doom mods like Brutal Doom. The game and the launcher (which allows you to download and set up mods directly on the headset) are both available now on SideQuest
This is as good a reason as any to get started with side-loading, if you haven't already!
