Antechamber

| Reflecting Pool |
Antechamber is a room located in the Chozo Ruins region of Metroid Prime. It is the room where Ice Beam is located. In a randomizer context, entering this room may softlock the game if you don't already have Ice Beam.
Bypassing the Ice Beam Door
This trick requires that you enter the room from out of bounds while the game thinks Samus is in Reflecting Pool. By ceiling warping in, it may be possible to collect the item and leave even without Ice Beam. This is done by shooting a charged Power Beam shot near the surface of the door. Because the game thinks Samus is in Reflecting Pool, the damage trigger that activates the door from the outside is functional, meaning that as long as Samus doesn't properly transition inside Antechamber, the game will register that the other side of the door has been interacted with and will freely open.
