Quantum Pause is a glitch that makes the player stuck in place while their speed and position can still be affected. It is mostly used to jump to later sections of the game.

It was found by 2838 on November 24th, 2018.

[section=How-to]

• Pause the game (preferably with the Open developer console button)
• Enter unpause into the console. The player can simplify this process with a button bound to the command toggleconsole;unpause To end the glitch, simply exit out of the menu screen.

Position

During the glitch, the player's position is almost fixed but it can be affected by many elements.

Props Props pushed towards or falling onto the player will only push them by a small amount, usually a few units.

NPCs Friendly NPCs will phase through the player when attempting to block their path. Hostile NPCs, however, can push you with their attacks; although like props, they can only push you by a bit. An exception to this is the Barnacle as it forcefully pulls the player upwards towards them using its tongue.

**Doors, elevators, trains, ... ** Scripted props such as doors, elevators and trains will push you similar to how they push away normal props. If you do the glitch while standing on a moving elevator or train, however, you will ride it like normal.

Miscellaneous Entities or operations that forcefully change your position such as a level change or teleport will still work like normal.

Speed

Like with position, the player's speed is almost fixed but it can be affected by knockback from:

• Explosive damage or enemies' attacks,
• Props pushed towards or falling onto the player.

Speed limit If the player is on the ground when they do the glitch, their speed will not go over 320 units per second. However, in the air, the player can receive speeds up to 19166.96 units per second.

Push When the player ends the glitch, they will be pushed in the direction and at the speed from knockback they had taken during the glitch. The player can use this force to jump to higher or later parts of the map.

Position

Because your position is almost fixed during the glitch, you can stay put in the air if you were to activate the glitch while in the air. This is particularly useful when you need to stay inside a trigger normally out of reach from the player. A good example of this is the second half of the Questionable Ethics skip.

Speed

The glitch is a good way to maximize the amount of speed taken from a damage boost (normally from a grenade or two). A good example of this in action is the Advanced Freezer skip utilizing 2 grenades, one on the ground and one held at a steep angle pushing the player towards a higher point of the map, which in this case, is the balcony after the Freezer.

You can also gain lots of speed from enemies' attacks such as the Human Grunts' punch; however it is harder to execute because of the random nature of NPCs and your vertical speed being dependent on your height relative to the Grunt's. This is best shown in the Canyon skip.
