'''Gathering Hall''' is a room located in the [[Chozo Ruins]] region of [[Metroid Prime]]. It is a large, vertical room with a lot of interconnecting parts. The bottom portion of the room has three of the four connecting doors, with the way to [[East Atrium]] at the top of the room. Above the door to East Atrium is a missile expansion, which requires the [[Morph Ball Bomb|Morph Ball Bombs]] to retrieve. The room also has a [[Secret World]], which serves as the basis for [[Ice Beam Before Flaahgra]].

The door to [[Save Station 2 (Chozo Ruins)|Save Station 2]] is blocked, and requires a missile to open. In the Double IS route, it is imperative that this door is opened at some point before performing the [[Infinite Speed]] trick in [[Magma Pool]], as this will allow for [[Lightshow]] to be quickly removed. In addition, this save station is also taken during segmented speedruns, so it is important to remove the blast shield there as well.

==General Information==
{{Layer Info|layers=Default</br>Poison Water</br>Clean Water}}

Defeating [[Flaahgra]] in [[Sunchamber]] disables layer "Poison Water" in this room, and enables layer "Clean Water".

Gathering Hall has many routes in all of the categories. Gathering Hall is an auto-load room, and loads in the sequence of: [[Gathering Hall Access]], [[Watery Hall Access]], [[Save Station 2]], then [[East Atrium]], in that order.

The missile in this room is sometimes referred to as the "kid's meal" missile. It is mainly gotten in the event that a runner wants to have extra missiles for the [[Sheegoth]] fight. If this missile is gotten, it loses 5 seconds.

==Speed Tech==
In Any%, the player must dash off of the [[Shriekbat|Shriekbats]] on the right towards [[Watery Hall Access]], then off of the [[Blastcap|Blastcaps]] to the door's left. On the first return visit, the player must climb the room, and shoot the Missile Shield on the Save Station for [[Lightshow Cancel]] after [[Magma Pool]] IS. Then, the player must go down to Arboretum after [[Incinerator Drone]]. If the player does not grab the Kid's Meal missile in Gathering Hall (often done in Segmented), it is faster to drop down, pause or open the map, then shoot the door and wait for it to open.

After cancelling [[Lightshow]] (using the pause/map trick on the save station door to save roughly 28 frames), the player can either boost through Gathering Hall or dash to the pipes as seen in this video. Laying a bomb in front of the door before rolling through and boosting to the save station is a faster strategy for those boosting back into Gathering Hall.

===Kid's Meal Missile Timing===
As shown in the video below, getting the missile in this room loses 5 seconds.

==Secret World==
This is one of the most important Secret Worlds in the run, as it is used to skip the puzzle in [[Energy Core]] and get to the [[Ice Beam]] early. See the page for [[Early Ice Beam]] to get an idea of how to do the wallcrawl.
===With Space Jump===
Use any platform near it to jump to the ubiquitous "Red Plant" in this room. Then jump towards the corner with a strange rock formation on it. Then simply use the slant on the rock to [[Slope Jump]] out of the level.

===Without Space Jump===
It is possible to do this secret world without [[Space Jump Boots]] by executing a difficult [[High Bomb Jump|HBJ]].

===Traversing to East Atrium Door===
Once on the seam of the room, the single most common thing to do is to head to the door leading to [[East Atrium]]. The video below compares three different strats that are used to do this.

===Quick Recovery Strat===
There may also be instances where you fail to get on the ledge, or it knocks you off. If this happens, use the strat in this video to quickly get back up.
