I was watching this video on YouTube, it was posted recently, and I got curious. The guy simulated a Helm’s Deep battle from The Lord of the Rings, but there’s something different — there are way more NPCs. Also, there’s a second wave of Orcs that invade the fortress, which is really interesting. I’ve never done that before. Which mod allows you to do that?
