With the PC version of the game installed and freshly updated, I'm finally picking away at Dark Souls. I'm liking it, but I think I'll pass on this new mod for the game, which makes the enemies nightmarishly relentless.
The mod, posted to Insane Difficulty by user JITD, makes enemies wander the map, allows them to see you from great distances, and has them follow you anywhere you go. In the video above, VaatiVidya takes a run through the game with the mod active.
Download it here, if you dare.
