This new method saves around 4-5 seconds, the glitch is not new, but the implementation in a speedrun is. It allows you to go trough walls, its like the Fortress skywalker glitch but in a weird death state

To trigger this do as follows:

• You need a healing item in your inventory
• Stand on the spring trap ( the one that pushes towards spikes in the celling)
• As you get hit and die to the spikes, mash all the attack buttons, the glitch works if you get a LOADING here
• As soon as you see the LOADING, press the select button then heal -Healing here prevents sub zero from falling and dying -Glitch activated, clip trough walls while alive

If somehow this can be replicated in another level it would be insane as there are other levels that can be greately exploited by going through walls
