A Hidden World (known unofficially as a Secret World) is an area in a Metroid game that is created through a glitch. In the 2D games they are often variations of a room, major area, or sometimes even the entire game; and in the Metroid Prime series they are areas outside the boundaries of a room. These are often completely black except for the room the player entered it from, which they can still see and re-enter if they walk through the wall. Hidden Worlds in the Prime series are often used in Sequence Breaking, most notably with the Early Ice Beam exploit.

Throughout the Metroid series

Metroid

Nintendo Power volume 29

In the original Metroid, Hidden Worlds were found by using a glitch called the Door Jump or by using a cheating device. Some of the hidden worlds were simply areas that got left out of the game. Others, reached by "flying" (using a cheat code or a hack) up an elevator shaft are versions of the place Samus would be, with the graphic palette of the area she just left. The reason is that when she rides an elevator that is the game's excuse to switch palettes, and so the Hidden Worlds that are entered by flying are really the actual place it resembles, and the game has not switched palettes. This explains why most Hidden Worlds in the game are stable.

Metroid II: Return of Samus

In Metroid II: Return of Samus, Hidden Worlds were often entered by using the Block Shifting Glitch (also known as the Select Glitch). It sometimes will move blocks out of the way so Samus can enter glitched rooms. As with the original Metroid, these Worlds are versions of the room Samus supposed to be, but filled with junk. Occasionally in these Hidden Worlds, disconnected but still functional parts of Save Stations can be found. In the Worlds Samus might also find enemies that are made of the wrong sprites. The Block Shifting/Select Glitch has limited use in speedruns.

Metroid Prime

In Metroid Prime, Hidden Worlds are accessed by going out of the boundaries by jumping on some elements that were not intended for this. It is possible to get into a hidden world in the Chozo Ruins Main Plaza, the Life Grove in Tallon Overworld, and the Ice Ruins East in the Phendrana Drifts, among others, by jumping onto certain blocks protruding from the wall. One common out of bounds technique performed is the famous Early Ice Beam before Flaahgra wallcrawl.

Metroid Prime 2: Echoes

In Metroid Prime 2: Echoes, most of same techniques from the previous installment can be used here. In rooms with pitfalls, should Samus fall below a certain height and within the Terminal Fall's boundaries, Samus will be placed back inbounds from wherever the game would normally decide.

With the introduction of the Screw Attack, one can use it to enter Hidden Worlds. One notable example includes Dark Transit Station.

Metroid Prime 3: Corruption

In Metroid Prime 3: Corruption, most of the same techniques from the first two Primes can be attempted here. Terminal Fall properties appear to behave identical to the previous installment.

With the addition of the Ship Grapple, Samus's gunship could also be used to access Hidden Worlds. One such example can be found within Chozo Observatory.

Using an advance out of bounds wallcrawl within Skytown, one can access the detached Spire Dock's event from the Escape Pod. Triggering the Spire Dock's event this way will automatically place Samus at the Spire Dock Pirate invasion scenario, thereby skipping the need to collect the Theronian Bomb components. This also prevents the Spire Dock in Skytown from being detached as it normally would.

A out of bounds area exists in Lift Hub. Using the Boost Ball within a certain broken elevator allows Samus to reach the large gate from the other side. She must move quickly as energy is rapidly decreasing.

Metroid Prime Hunters

In the Multiplayer modes of Metroid Prime: Hunters, certain glitches or cheats bring the Bounty Hunter into similar Hidden Worlds to Prime. The simplest glitches are achieved by using an explosive weapon to blast the hunter through certain spots in walls. This can also be done in Adventure Mode, among other exploits usually involving usage of the Morph Ball, though leaving the boundaries of certain areas can sometimes lead to an instant Game Over.

It should be noted that this is considered cheating when done online, as the person outside of the stage can shoot at those who aren't outside the stage, but those in the stage cannot shoot the people who are outside.

Metroid: Other M

In Metroid: Other M, it is normally impossible to reach out of bounds areas, due to having many enclosed surroundings or rooms within the general setting. Using cheat codes can allow Samus to phase through solid walls, but if she reaches a certain low elevation zone in any room, she will instantly receive a Game Over (she can still move until the screen transition to the Continue Screen concludes).

Metroid Prime Remastered

In Metroid Prime Remastered, room layouts have been adjusted so that Samus no longer can float or be stuck in mid-air due to a room's layout. Similar to Metroid: Other M, should Samus fall below a certain elevation zone, she will immediately die, causing a Game Over. The roof geometry has also been altered, making it more easier for Samus to fall back inbounds should she stand on a roof flooring from out of bounds. These changes make certain Sequence Breaks much more difficult to achieve.
