Someone Spent 10 Months Reverse-Engineering Dark Souls To Destroy Other Players

Though Dark Souls was released in 2011 and Dark Souls 3 is only a few months away, the community hasn't moved on. Recently, someone created an AI for PvP combat to invade other players and totally wreck them. Meet...The King.

Created by Dark Souls fan metal-crow, The King is the result of 10 months spent reverse engineering From Software's hardcore action game.

"Only a few hundred, dedicated, and at this point extremely skilled, people remain who regularly PvP," wrote metal-crow on reddit. "I don't know how much longer the game has before the online audience becomes too low for random battles, but I wanted to give perhaps the greatest game ever made the send off it deserves. A sentinel, the final guardian of this game. Something that can surpass any human in a duel."

metal-crow has released the source code, allowing other people to unleash other AIs into the world.

They're also going to continue work on The King, trying to make it deadlier.

"There are plenty of bugs and imperfections in the AI, and it will likely be beaten," they wrote.

If you'd like to know more about how metal-crow created this, there's a deeper writeup in the game's source code. Here's an excerpt:

"In order to have the AI do anything, i needed to be able to feed it data about the game state. The simplest and most direct way of doing this is would be to have it watch various variables in the game code, such as the enemy's x and y location, and then use that with the AI logic. However, since the game's code isn't open source, i needed to reverse engineer anything i wanted to use.

The first step i took was finding the basic variables i knew i needed, and were the easiest to find. By using a second computer, i could connect to myself and have a test enemy player i could work with. Using the program Cheat Engine, which is a powerful debugging and memory scanning software, i was able to quickly find the enemy's x and y location variables, and a few other simple values. Running a pointerscan on these values and cross referencing these scans, i was able to find the executable base address that the game always used for to point to the enemy struct, and the pointer paths to the variables."

Never change, Dark Souls fans.


    that 90's game with the same movement restrictions from the 90's, so lame.

    So if it can be beaten... What's the point of revealing it now?

      Right? It's nothing more than a random npc. Not some ultra advanced ghost character that can wreck through players undefeated. The guy even killed him with a few parries. Big "meh" imo

        The point isn't that it's a dark souls 2 bot. the point is that the reverse engineering and programming skills needed to achieve this are nontrivial and this guy used this as a
        fun sideproject to learn how to do these things.

        Nobody in their right mind would do this to spite people.

        Although they could.

          Cool, so when will Kotaku start covering all the hard work people put into making Aim bots?
