Black Knife Simulator Description
Black Knife Simulator is a free browser recreation of the Roaring Knight boss fight from Deltarune, rebuilt by a fan with the game's own assets. Black Knife is the name of the track that plays during the real battle, and the fight here follows it close: Kris, Susie and Ralsei take on the knight in a sequence of party commands and bullet-dodging, with the original's sprites, music and attack patterns reproduced beat for beat. If you have played Chapter 3, this is that fight, runnable in any desktop browser with no download. Five modes frame the fight. Normal is the battle as written; Practice lets you learn individual attacks without the pressure; Hitless ends your run the moment you take a hit; Endless chains the knight's attacks for as long as you can last; and Single Attack drills one pattern at a time. Before each attempt you can adjust the party's equipment and items, so the fight plays out with the build you want. The simulator was built by a fan who goes by RADI0, using extracted game assets to match the original encounter as precisely as possible, and it runs entirely in the browser: a small pixel-art page that loads in seconds, with support for gamepads and on-screen buttons on phones. It is a fan project with no official connection to Toby Fox, and if you enjoy it, the real game is worth your time. Black Knife Simulator has nothing to do with football. This page embeds the simulator from the developer's own site and hosts nothing. Deltarune is © Toby Fox. No download, no account.
