Sky Temple Gateway

	Connecting Rooms
	Gateway Access Sky Temple Energy Controller

Sky Temple Gateway is the final room of Metroid Prime 2: Echoes, containing the final encounter with Dark Samus. It is the room in which Samus uses all 9 of the Sky Temple Keys to go to Sky Temple Energy Controller. If Samus arrives to this room without having obtained all of the keys, the game will give Samus hints on where to obtain the remaining keys. Once all three phases of the Emperor Ing have been defeated, the final boss sequence starts, and Samus will be on a timer to defeat Dark Samus for the final time in the game.

Much like in Hall of Honored Dead, the portal is purely decorative and doesn't have any function.

There is a Secret World in this room that requires Screw Attack.

General Overview

Lock to Sky Temple

This room has a large set of conditional relays that individually check for each Sky Temple Key within Samus' inventory. When the game sees that each key has been acquired, it will then spawn the trigger that allows for Samus to get to the Sky Temple. With current knowledge, there is no way of circumventing this.

Dark Samus Fight

When the final boss sequence is active, the room's layer will be changed so that two large walls of phazon block both the (inactive) portal and the way leading to Gateway Access. Additionally, an energy barrier will spawn at the edge of the arena. While impossible under normal circumstances, if Samus were to head into Gateway Access and reload the room, it would render the game unbeatable.
