Rude Buster is Susie's signature rude spell in Deltarune, the indie role playing game created by Toby Fox and first released with Chapter 1 in 2018. Costing TP in battle, it sends a powerful axe projectile at a single enemy and became one of the most clipped combat effects from the game. As Deltarune fan videos, battle recreations and meme edits spread on YouTube and social platforms, creators began isolating the hit sound on its own for other fight scenes.
About this sound
The Rude Buster hit sound effect from Deltarune, the sharp slashing impact from Susie's axe attack, used in edits for powerful blows and turn based battles.
This is the impact sound that plays when Susie's Rude Buster attack connects in Deltarune. In under a second it layers a sharp whoosh, a heavy magical slash and a bright percussive thud that cuts off cleanly. The attack animation throws a red axe shaped projectile across the screen, and the hit lands with the visual flash, making the damage feel much weightier than a normal strike. It is short, punchy and instantly recognisable to players, which is why it works so well as a standalone hit marker in fan edits.
