Sandbox of Voices and Sounds

Step into FNF Character Test Playground 4 to experience a wide-open testing space where every tone, rhythm, and visual feedback is represented like a miniature recording studio. Instead of forcing players into intense battles, the mod opens up a more free-form approach, allowing for character-specific vocal exploration.

Sound Lab Exploration

FNF Character Test Playground 4 acts as a sound lab that allows each character's voice to be activated via the controls. Each character has its own unique voice tone, from compressed, high-pitched to the Sonic.exe series' signature glitch. Small movements are synchronized with each key press, creating the feeling of experimenting with multiple layers of sound in a closed room.

Characters In Rotation

• Sonic.exe's lineup with a full range of voice variations.
• Characters from Sandboxin, QT, Cyrix, and Arch add a rich range of sounds.
• Each character has a different response when triggering long notes or repeats.

Interaction Guide

The test field has no limits, but the control tempo is clearer when using WASD or the arrow keys to trigger each sound. Some characters have their own vocal groups on long notes, creating a studio-like echo. Enter allows you to change scenes or pause when you want to change characters.
