	This is done by pressing backwards during the knockback that initially knocks Samus out of [[G-Mode#G-mode Immobile\|G-mode immobile]]. The backwards press must be during the knockback frames, so is a five frame window. If done way too early, Samus will turn around and then be hit; if done slightly too early, Samus will turn-around kago the hit; if done too late, Samus will turn around after the knockback frames.		This is done by pressing backwards during the knockback that initially knocks Samus out of [[G-Mode#G-mode Immobile\|G-mode immobile]]. The backwards press must be during the knockback frames, so is a five frame window. If done way too early, Samus will turn around and then be hit; if done slightly too early, Samus will turn-around kago the hit; if done too late, Samus will turn around after the knockback frames.

	If the fast G-mode method is done, with less than 5 Energy in Reserves, then the frame window for entering G-mode interacts with the frame window for pressing backwards. With n health in reserves, the number of frames that backwards can be pressed is 8-n. There must also be a short pause between X-Ray release and pressing backwards. The frame window for pushing backwards is always in the same spot (no matter when X-Ray is released), and is always 1 frame after the last frame that X-Ray can be released (if backwards is pressed during this 1 frame instead, then Samus turn-around kagos the knockback). In other words, the following are the valid input patterns after the transition (with D meaning dash must be pressed, d meaning dash may be pressed, < meaning backwards must be pressed on one of these frames, and _ meaning an empty frame):		If the fast G-mode method is done, with less than 5 Energy in Reserves, then the frame window for entering G-mode interacts with the frame window for pressing backwards.

	The variable number of frames that one must wait dependent on X-Ray release can make this ~~obnoxious~~ for timing purposes.

If one is practiced at entering G-mode, 2 Energy may feel the easiest, where the window for pressing backwards (6 frames) is much longer than the waiting period (1 or 2 frames).

	This is a one time Morph: As soon as Samus unmorphs, the trick would have to be done again to be able to Morph. While in this morphed state, Bombs, Power Bombs, and Spring Ball may be used. It is still G-mode, so in order to break Power Bomb blocks one must lay a power bomb, unmorph, and then cancel G-mode.

	With this technique, without going [[Out of Bounds]], and in the usual Super Metroid layout, 62 items may be collected RTA without Morph.

			===Low Energy G-Mode With Heat===

			Heat damage will not apply to Samus while in G-mode. This often requires G-mode Immobile to have sufficient Energy to leave a room after cancelling G-mode. It is possible to have low Energy applications in heated room without heat protection or a Crystal Flash a few ways, although it is only useful in puzzles, randomizers, or hacks:
			* Bypass the door shell, to prevent leaving G-mode in the heated room;
			* Remote acquire an item while next to the transition in an open door (likely the one which was entered from), cancel G-mode and touch the transition before the door closes (1 Energy loss);
			* Collect an Energy drop from an enemy just after canceling G-mode, before leaving (with a pause abuse).

			Note that enemy drops will only spawn when exiting G-mode if they have not yet been overloaded. This is not the same as overloading PLMs. There are 18 spaces available and one is used for each enemy projectile that is spawned and one is used for each enemy drop.

			There may also be some niche use where overloading drops is beneficial, such as letting an enemy spawn 18 projectiles to then prevent other enemies from spawning projectiles that may be in a more impactful locations.

'''G-mode''' (short for ''Grey mode'' or ''God mode'') is one of the three X-Ray Scope glitched modes, the other two being [[X-Mode]] and [[R-Mode]].

It has some very powerful effects, many of which require specific setups and are limited to certain scenarios. Some of these include: convert some blocks and sand tiles to behave like air; prevent gates from spawning; prevent taking heat damage; prevent a door from closing behind Samus on room entry; and even morph without the Morphing Ball item.

	For speedrun purposes, G-mode is mostly a time save for low% categories. It is used in all optimal routes of 14% categories that collect X-Ray: [[14% xIce]], [[14% xChargeless]], [[14% xSpeed]], and [[14% xAmmo]]. In addition to simply being a faster method, in 14% xChargeless, 14% xPb and a theoretical PAL-only route of 14% xSpeed, it is required to avoid [[L+R Walljumping]].

	If dash is released very early, nothing notable will happen. If dash is released late, then instead R-mode will be activated.

If successful, the door will not close behind Samus (if at a transition where there is not a door, see [[G-Mode#Effects\|Effects]] to figure out how to determine it was successful in other cases).

	~~Based off the above description~~, ~~it is fastest to enter~~ G-mode ~~with a very small amount~~ of ~~Energy in Reserves. For most applications~~, it is ~~usually~~ optimal to have 4 Energy in Reserves. See the below sections for a discussion on this.		With 5 or more Energy in Reserves, G-mode Immobile will be entered. Because of this, it is generally optimal to have 4 Energy in Reserves. See the below sections for a discussion on this.

			===G-mode Immobile===

			When G-mode is activated, Samus will be unable to move until knockback frames...knock her back.

			Since knockback from an enemy lasts 5 frames, if Energy in Reserves is less than 5 then this happens automatically.

			If Energy in Reserves is at least 5, though, then Samus will be unable to move until an enemy hits her (or G-mode is canceled by using X-Ray). Thus, one must wait until an enemy hits Samus.

			While immobile, Samus is only able to rotate in place and shoot. The options for getting hit by an enemy include waiting for an enemy on-screen to hit Samus or waiting for a global enemy to reach her. Shooting a Super can be used to knock an enemy off a wall or platform to reach Samus.

			When getting knocked out of G-mode immobile, do not hold forwards. This will cause a downwards knockback which may immediately ground Samus and she may still be immobile. This applies to both the low health version (with the automatic knockback), and when waiting for an enemy.

	===The Frame Window===		===The Frame Window===
Line 52:		Line 64:

	* If the amount of Energy in Reserves is less than 12, then the frame window is as soon as you have control over Samus after the transition. Thus, if X-Ray is released too early, it will simply never be used.		* If the amount of Energy in Reserves is less than 12, then the frame window is as soon as you have control over Samus after the transition. Thus, if X-Ray is released too early, it will simply never be used.
	* If the amount of Energy in Reserves is greater than 11, then the frame window is the last 3 frames of health entering Samus' Energy Tanks. ~~If we let n be~~ the amount ~~of health entering her tanks (so n is the minimum~~ of Energy ~~in Reserves~~, and ~~the total of 99 + 100 * # of Energy Tanks), then the first frame where dash can be no longer held is when Samus' Energy is n-2, n-1,~~ or ~~the first frame when her Energy is n~~.		* If the amount of Energy in Reserves is greater than 11, then the frame window is the last 3 frames of health entering Samus' Energy Tanks. This includes the frame when Samus first hits the final amount of Energy that she will end with, and either one or two frames earlier.

	Note dependent on input lag, when X-Ray must be released could appear to be different. Visually, for entering G-mode when Energy in Reserves exceeds 11, the X-Ray Scope re-widens after the Reserves have finished deploying. The three frame window is immediately before this happens.		Note dependent on input lag, when X-Ray must be released could appear to be different. Visually, for entering G-mode when Energy in Reserves exceeds 11, the X-Ray Scope re-widens after the Reserves have finished deploying. The three frame window is immediately before this happens.

	~~From this discussion, it sounds like an~~ optimal amount of Energy in Reserves is 11, where the frame window is at a maximum of 14 frames. However, due to the next section on G-mode immobile, most applications of G-mode have 4 Energy in Reserves (with a 4 frame window) and the remaining applications have full Energy in Reserves (with a 3 frame window).		The "optimal" amount of Energy in Reserves can be defined in several different ways:
			* If it is possible to perform the needed actions at 4 Energy, it is generally optimal to have 4 Energy in Reserves: This way, Samus may move immediately, and the frame window is maximized.
	~~===G-mode Immobile===~~		* If there is an enemy that can re-mobilize Samus and that enemy can deal less than 11 damage, then having 11 Energy in Reserves will significantly increase the frame window at the cost of being slower.
			* If the the actions require having a larger amount of Energy, it is generally optimal to have full Reserve Energy, but Samus will be immobile and require an enemy to hit Samus.
	~~When G-mode is activated, Samus will~~ be ~~unable to move until knockback frames...knock her back.~~

	~~Since knockback from an enemy lasts 5 frames, if Energy~~ in ~~Reserves is less than 5 then this happens automatically.~~

	If ~~Energy in Reserves is at least 5, though, then Samus will be unable to move until an enemy hits her (or G-mode is canceled by using X-Ray). Thus, one must wait around until an enemy hits Samus.~~

	~~Therefore, in cases where~~ it is possible to perform the needed actions at 4 Energy, it is optimal to have ~~only~~ 4 Energy in Reserves: This way, Samus may move immediately, and the frame window is maximized.

	~~In any other case,~~ the actions require having a larger amount of ~~health. Thus, usually a full health G-mode would be performed instead. Then one must wait for a (usually global) enemy to hit Samus.~~

	~~The maximized frame window at 11~~ Energy ~~in Reserves is more of a curiosity. If this is used~~, ~~then~~ it is ~~the worst case: Samus has very low~~ Energy, ~~and she cannot move until she gets hit by an enemy.~~

	~~When getting knocked out of G-mode immobile, do not hold forwards. This~~ will ~~cause a downwards knockback which may immediately ground Samus and she may still~~ be immobile~~. This applies to both the low health version (with the automatic knockback),~~ and ~~when waiting for~~ an enemy.
