Shutters,[1][2] also known as Metal Poles,[3] are a type of mid-room barrier that appear in Super Metroid, Metroid Fusion, Metroid: Zero Mission, and Metroid Dread.


Shutters block progress (usually directly in front of a door or hall) until an upgrade or path around them is found. If Samus has the Wave Beam in Super Metroid and Metroid Fusion, it will penetrate the barrier and can open it from the "wrong side".

In Super Metroid, there are also shutters with green lights, indicating they can be opened with a Super Missile. The Hyper Beam can destroy shutters with one shot, as witnessed in a room behind Mother Brain's chamber.

In Metroid: Zero Mission, they appear throughout Chozodia and the Space Pirate Mother Ship, blocking Zero Suit Samus' way when the Pirate Alarm System is active. They cannot be lifted by Samus. Instead, she must wait for the Zebesian Space Pirates to lose sight of her, at which point they will automatically open.

In Metroid Dread, Shutters are marked with lights that glow yellow when open and red when closed. Certain Shutters lock off rooms when Samus encounters Twin Robot Chozo Soldiers in Ferenia and Burenia, preventing her from escaping. These Shutters automatically reopen once the robot enemies are destroyed. Other Shutters are triggered by pressure-sensitive Shutter Platforms,[2] which close the door when Samus steps foot on them and only reopen a few seconds after she steps off the platform. Shutter Platforms can only be bypassed with the Flash Shift. In various E.M.M.I. Zones, Shutter Platforms can either be exploited to block the path of a pursuing E.M.M.I., or they may hinder Samus while she is trying to escape.


Super Metroid[]

"There are several metal poles in the passages of Zebes. The color of the lights above these poles should give you an idea on how to make them move out of the way."

Metroid Fusion[]

"Shutters can be opened by shooting the lamps with beams."


  • There is a glitch in Super Metroid commonly known as the "Green Gate Glitch", where Samus must run up to a green-lighted shutter, jump and shoot diagonally at a certain spot to open it the wrong way. This is used in many instances, such as getting the Screw Attack early. However, this glitch only works on gates with left-facing lights.
  • A similar obstacle to shutters appears in Metroid: Other M during the final Countdown sequence, though they are gates instead of poles. They appear in two hallways and are consistently closing. Zero Suit Samus is required to slide under them, but if she cannot make it, she can fire a charged shot of the Paralyzer or multiple uncharged shots.
  • Red-lighted shutters and yellow-lighted shutters appear in the data of Super Metroid, accessible via the Super Metroid Integrated Level Editor (SMILE). However, neither of these two shutter variants are actually encountered in the game.
