Run 3

Defy gravity, outrun the void, and explore a galaxy of crumbling tunnels — the endless runner that never stops surprising you.

Game Overview

Run 3 is a space-themed endless runner platformer developed by indie developer Player_03. Originally released on mobile in December 2013 and brought to browsers in June 2014, Run 3 is the third and most ambitious entry in the acclaimed Run trilogy. You take control of a small alien navigating a series of crumbling tunnels floating in the void of outer space — miss a step and fall off the edge, and you're lost in space forever.

What truly sets Run 3 apart is its gravity rotation mechanic: run far enough to the left or right, and your character shifts to the wall — or even the ceiling. Mastering this opens up incredible movement options that keep every level fresh. Through years of consistent updates, Run 3 has grown from a simple runner into a deep platformer complete with a branching level map, 10 unique characters, a full in-game storyline, and a custom level editor.

Pro Tips for Survival

  • Use the walls aggressively — When tiles ahead are missing, shifting to the wall or ceiling can save your run. It's your most powerful tool, not just a last resort.
  • Jump earlier than you think — Gaps look smaller than they are at high speeds.
  • Beware of ice — Ice tiles boost your speed but heavily reduce control; brace yourself before you land on one.
  • Watch for crumbling chains — Step on a crumbling tile (they flash before breaking) and adjacent ones may collapse too. Plan your landing zone fast.
  • Match the character to the level — Struggling with gaps? Use the Pastafarian's light bridge. Keep breaking tiles? Use the lightweight Child.

Game Modes & Progression

Explore Mode

Navigate a branching Galaxy Map filled with 309 handcrafted levels across 21 distinct level sets. Start in the Main Tunnel and push deeper into increasingly complex branching paths. Run 3's full in-game storyline unfolds here through character interactions. Completed levels can always be revisited to practice tough sections or pursue alternate routes.

Infinite Mode

No finish line. No mercy. Infinite Mode drops you into an endless randomized sequence drawn from 325 pre-built levels, with your total distance tracked in real time. Power Cells scattered throughout increase in value the farther you travel, and collecting them lets you revive your run by switching to a backup character mid-fall.

Shop & Level Editor

Spend your earned Power Cells in the Shop to unlock characters, costumes, Infinite Mode upgrades, and even a Level Editor. The Editor is a creative sandbox for dedicated fans: design your own tunnel, set your own obstacles, and run through your own custom creations.
