{{Connecting Rooms|rooms=[[Agon Transport Access (Sanctuary Fortress)|Agon Transport Access]]</br>[[Central Area Transport East]]</br>[[Culling Chamber]]</br>[[Minigyro Chamber]]}}'''Hall of Combat Mastery''' is a room located in [[Sanctuary Fortress]] in [[Metroid Prime 2: Echoes]]. It contains a missile expansion and a [[Secret World]] that requires [[Screw Attack]].

==Early Missile Expansion==
It's possible to skip all of the morph ball tunnel sequences in the room and get the missile expansion early. There are a few ways to do this.

===Instant Morph Method (Spider Ball) ===
By doing an [[Instant Morph/Unmorph|Instant Morph]] on the [[Spider Ball]] track, you can instantly connect to it, allowing for easy access to the item.

===Screw Attack Method===
If you don't have Spider Ball but have Screw Attack, this alternate method also works.

==Spider Ball Skip==
It's possible to bypass the spider track and go to [[Central Area Transport East]] without having to go into [[Culling Chamber]]. This can be done both ways.

===Slope Jump Method===
By doing a [[Slope Jump]] into an Instant Morph, you can get over the gap.

===Screw Attack Method===
With this method, there are two different approaches for both sides of the room. The first approach requires a [[Bomb Space Jump]], while the approach on the other side takes advantage of the Cobalt Translator scan point that is standable.

==Secret World==
By performing a [[Screw Attack]] into one of the [[Morph Ball]] tunnels, it is possible to go out of bounds.
