GFMC Compound

GFMC Compound is a room in the Temple Grounds, containing the Missile Launcher.

101% Trick
A ghetto jump can be used to climb up to the Missile Door without first activating the cutscene. This can be used to collect the Missile Launcher before viewing the cutscene.

Collecting the Missile Launcher and then activating the cutscene will respawn the Missile Launcher, allowing you to collect it a second time. This will give you 10 missiles instead of just 5, and allow you to reach a item % of 101. However, the last missile expansion collected will keep you at the cap of 255.

This also works if a different item is in the crate (i.e. in randomizers). Exceeding the energy tank limit of 14 or power bomb limit of 10 is not possible.

Missile Expansion
The missile expansion on top of the ship does not spawn until after defeating Space Jump Guardian in Judgment Pit.

It can reached without Screw Attack by Space Jumping off the ledge near the red Missile Door.

Translator Door
Despite looking like it requires Emerald Translator, the translator door only requires Violet Translator. It does not spawn immediately when you first visit the room; avoiding the cutscene can allow you to reach Fortress Transport Access early.

Secret World
Screw Attacking into the morph ball tunnel provides access to a secret world.
