Doom 2: Map 03 The Gauntlet, WORLD SPEEDRUN RECORD by hitting a secret switch you can only use once
Run around the blue armour and hit the exact right spot on the floor, this will open a little switch that once it shuts you will have to start the level over if you miss it, I wish I had better aim! Once the switch is pressed, the silver door in the starting room will open and close one time only as well! PS you have to perform this shortcut EXACTLY, you can't go back right after getting the blue armour or the switch will close, you have to take this path to the switch and back and FAST Tricky tricky!
