Disclaimer: While I am personally Christian, I’m not trying to Bible-thump here. It’s just something that I think would make a genuinely interesting premise for a mod.
What it says on the tin. Something like an overhaul that places the game in a Biblical apocalypse. I feel like it would be cool to see, especially with some of the weirder elements of the Book of Revelation. Imagine having to purify water because it’s been poisoned by the fallen star Wormwood, or taking shelter from a rain of fire, or fighting desperately to survive an attack by the demonic cavalry. Food for thought, is all.
