Description

Game Introduction

FNF vs Detra’s Mental Decimation Online Rhythm Game is a fan-made mod for Friday Night Funkin that introduces two unique characters. The first character has a gray body, black clothes, and an orange cape with orange eyes. In the second week, this character evolves into a bicolor form—half black, half gray—with a red cape and tie. You’ll battle through seven original songs: Retricus, Covetous, Terminus, Embark, Facade, and Compel. The mod was developed by SkullZMinus, with original programming by ninjamuffin99, art by PhantomArcade 3K and Evilsk8r, and music by Kawai Sprite. It’s a family-friendly rhythm challenge that tests your timing and reflexes.

How to Play

Use the arrow keys on your keyboard to match the rhythm of the songs. Press the correct notes when they reach the hit zone to score points and keep your combo going. Each song has a unique beat pattern, so listen carefully and stay focused. The game features two weeks of content: Week 1 has four songs, and Week 2 (labeled BONUS) has three songs with the evolved character. Keep your accuracy high to win each battle and progress through the story.
