Minecraft Custom Map

I was playing this minecraft custom map with my friends, but it was extremely realistic, so realistic that I could feel everything and it looked just like real life, I remember it started with being in some sort of cave but it wasn't completely underground, and there was a thunderstorm, then we noticed more and more weapons falling from the sky, tridents, spears, swords, cutlasses and a lot more, somehow we knew those are the weapons the gods gave up to start war on us
