The "Sidehopper hall" is a room in the Main Sector. It appears in Metroid: Other M.


This is a straight walkway that connects the rest of the Main Sector to the Main Elevator that leads to Sectors 1, 2, and 3. It has very simple architecture: several forward-facing buttresses lining the walls, a railing in front of them with blue lights in between each buttress, blue fluorescent lights on the ceiling, and a black-colored floor. Notably, several sections of it on either side are transparent and covered with panes of glass that have a hexagonal pattern across them.

In the center of the room, the railing on the right curves into the wall and stops beside a Desbrachian gate, which cannot be opened on the first visit as Samus is not authorized to use her Power Bombs.

Samus Overblasts a Sidehopper.

When Samus enters the room for the first time, the door to the Main Elevator is locked and there are two Bulls in the room. As she moves closer, two Sidehoppers appear out of nowhere (as there is nothing in the room for the Sidehoppers to emerge from). Although an on-screen tutorial for the Overblast is given in the slender walkway previously, it appears on-screen again here as the game encourages Samus to dispatch the Sidehoppers with Overblasts. Once they are defeated, three more Sidehoppers spawn approximately six seconds later and Samus is required to kill them as well. Once they are dead, Samus can enter the Main Elevator room.

On her return to the BOTTLE SHIP during the post-credits sequence, Samus can continue her journey to Adam's helmet through this room. Once she returns from the Cryosphere via the Main Elevator (or another sector if she has decided to collect expansions), she can use a Power Bomb in this room to summon the Desbrachian and destroy it. Through the gate, she will find a corridor leading to an elevator to the Control Bridge, where she encounters Phantoon for a second time. If the save file is reloaded after completing the post-credits quest, the Desbrachian will remain dead.

"After exiting the room with the elevator, you’ll be trapped inside a long corridor with Reos and several Side Hoppers. Use Overblast to eliminate all the Side Hoppers and the door on the opposite end of the corridor will unlock. Enter the Main Elevator room at the far end of the corridor to access Sector 1."
Note: "There is another circular hatch in this long corridor that you cannot access just yet. Make a note of it, but don’t worry about it for now."

"Leave the Main Elevator room and explore the halls leading back toward the docking bay. Find the dormant Desbrachian on the right and wake it with a Power Bomb. Defeat it quickly, then proceed through the hatch on the right."
