Batman: Arkham Knight PC mod makes flashback Joker playable
Batman: Arkham Knight PC players can step into the shoes of the Joker as he appeared when he - well. Spoilers.
The Arkham Knight Mesh-Swapping mod enabling this experience was created by Tchi6, and has been used for all sorts of shenanigans like making game director Sefton Hill playable.
YouTuber Heitor Fraga loves putting together new playable characters using this tech. As you'll see below the Joker isn't just a reskinned Batman; his moveset is derived from the Red Hood DLC.
Click through to YouTube and check the video descriptions for more details on how these characters are created and how to get them in your own game - with all the usual caveats about non-official external downloads, of course.
Thanks, Kotaku.
