It’s like the bible but if the apostles were all hot beefcakes and instead of duping fish or whatever jesus decided to use his psychic powers for galactic genocide.

This is literally what happens when I ask friends what WH40K is. The only thing I understood is that everyone kills each other.

Oculus truly is the GOAT

I’ll just ask my autistic friend. It’ll be more detailed and he gets to rant

Honestly, the only “lore” videos you need to know are from this guy:

Key points:

1. The “Spess Mehrens” are the good guys.
2. Leader of the Imperium of Man (basically the 40k Federation) is the “Emprah”
3. The most superior tactic for engaging foes is a maneuver that the Codex Astartes (like the Art of War for 40k) names “Stiehl Rehn”
4. No other factions besides the Spess Mahreens matter and you should never buy them.
5. The best thing to do is to be “The Emprah’s Fureh” and smite all his foes otherwise you’ll die in shame having “Fehled the Emprah”

Oh yeah, and machines have souls and they do much better when you praise and worship them and anoint them with holy oils, so make sure to do that if you ever get isekai’d into the 40k universe for the like 45 seconds you’ll probably be able to stay alive for.
