Play Dark Souls: Remastered as NieR:Automata's A2: her real model, sword and combo moves, read from your own NieR install.
Play Dark Souls: Remastered as A2 from NieR:Automata. Her real model, her Type-4O Sword and her NieR moves are read at launch from your own NieR:Automata install, and the Chosen Undead is hidden so A2 walks Lordran in his place.
What you get
Controls: RB / left click for light, RT / right click for heavy, B / Space to evade. Dark Souls keeps its own movement, roll and menus.
Known limits (v0.1): enemies take A2's damage but don't stagger from it. Your equipped Dark Souls weapon still swings invisibly on the same buttons. A2 is drawn over the HUD and has no shadow.
