Using the JET-Board in the Weapons Factory slime to activate Invulnerability Glitch.

Invulnerability glitch, sometimes called invuln, is a bug that allows Jak to stay alive while in a dead/dying state. The glitch is primarily used in the Any% and Gunless categories to assist with boss fights and make specific skips possible.

Tutorial

Technical

The invulnerability glitch has two different states: State 1 and State 2. More commonly referred to as Invuln 1 and Invuln 2. To enter State 2, Jak must first enter State 1 and then take fall damage.

There are a few known ways to enter State 1 invulnerability:

  • Dismounting the JET-Board in a death plane on the frame Jak should die
  • Taking damage on a certain frame during the Restart Mission sequence
  • Swimming up through a plane of Dark Eco (diving into the side of a Dark Eco pool)
  • Spin kicking and shooting (Wastelander Move) in lava on the same frame you should take damage

To exit the invulnerability glitch:

  • Bonk into a wall
  • Clip into an enemy character model as it is attacking
  • Use the warp gate
  • Die in the void
  • Restarting a mission from the pause menu
  • Loading a save file
  • Dying from too much fall damage

Invuln 1

  • Enemies will no longer target Jak.
  • Jak can't pick up ammunition, skull gems, eco, or precursor orbs.
  • Jak can't use vehicles, weapons, Dark Jak, or the JET-Board.
  • Jak can't speak to non-playable characters or side mission holographic terminals.
  • Jak can't ledge grab.
  • Jak can walk on all death planes except the void.

Invuln 2

To achieve the second state of invulnerability, Jak needs to take fall damage. Or splat as most people call it. The splat animation that occurs when taking fall damage acts as a check that lets the game know that Jak is still alive. After the splat, all of the side effects of Invuln 1 will be negated except the main invulnerability effect.

Discovery

The JET-Board method of entering invulnerability State 1 was discovered by Djtomjak73 on September 11, 2015.

OutrageousJosh discovered a consistent way to enter State 1 by taking damage on an exploding zoomer during the Restart Mission sequence.
