Run 3 - Defy Gravity in an Endless Space Adventure

Run 3 is a browser-based endless runner and action-platformer developed by Joseph Cloutier. Set within a mysterious network of floating tunnels in space, the game challenges players to navigate dangerous pathways, leap across massive gaps, and use gravity-shifting mechanics to survive. With its unique level design and innovative movement system, Run 3 remains one of the most popular platform games ever released for web browsers.

Gameplay Overview

The most iconic feature of Run 3 is its gravity-shifting mechanic. When you jump onto a wall, the tunnel rotates and that surface becomes your new floor.

This allows players to:

Avoid dangerous obstacles.
Create new paths through levels.
Reach hidden routes.
Bypass missing floor sections.
Solve navigation challenges creatively.

Mastering tunnel rotation is essential for surviving the game's later stages.
