As is customary for Metroid games, Metroid Dread features a wide variety of doors and blocks that will bar players' progress at various points throughout the game. Each one requires a different tool or technique to overcome, allowing the developers to hide the entrances to secret and late-game areas in plain sight from the very beginning of Samus' adventure.

As well as nine different types of doors, Metroid Dread also features six special dome-shaped door covers that can prevent players from progressing. These are typically countered using beams and missiles, while the majority of the game's nine block-types can only be overcome with the help of bombs or special techniques.
Quick Links
Every Type of Door in Metroid Dread
Power Beam Door
Power Beam doors are yellow and can be opened with a single shot from Samus' arm cannon.
Charge Beam Door
Charge Beam doors are orange and can only be opened once players have found the Charge Beam in Artaria.
Sensor-Lock Door
Sensor-Lock doors will slam shut if they detect movement. Players can get around this by using the Phantom Cloak.
Shutter Door
Shutter doors will slam shut if Samus steps on the yellow platform in front of them. Players can avoid this by using the Flash Shift to pass through them without touching the ground.
Thermal Door
Thermal Doors will only open when connected to a source of hot magma. In certain regions, players can use special devices to redirect the flow of Planet ZDR's magma and get them open.
Grapple Beam Door
Grapple Beam doors are black with a glowing blue triangle on them and can only be opened with the use of the Grapple Beam.
E.M.M.I. Patrol Zone Door
E.M.M.I. Patrol Zone doors are typically made up of a white mosaic holograph and can be freely passed through by players. If the E.M.M.I. patrolling the zone is on alert, however, the doors will turn solid and begin to glow red, which will prevent Samus from passing through. To unlock them, players will need to escape or hide from the robot until it is no longer pursuing Samus.
Central Unit Door
Central Unit doors feature a bright white circle of light on them and can only be opened with the use of the Omega Cannon.
Boss Door
Boss doors are made up of living worm-like creatures and will attack players if they get too close. To kill the creatures and open the doors, players will need to execute a counter attack when they strike.
Every Type of Door Cover in Metroid Dread
Missile Cover
Missile covers are red and have a honeycomb-like design. As the name suggests, they can be destroyed with a single missile.
Super Missile Cover
Super Missile covers feature a green mesh-style design and can be destroyed with a single Super Missile.
Storm Missile Cover
Storm Missile covers feature five green dots and can be destroyed by targetting the five corresponding green lights that are nearby with a Storm Missile.
Wide Beam Cover
Wide Beam covers are orange and feature three dots on the front. To destroy them, players will need to hit them with a charged shot after finding the Wide Beam in Dairon.
Plasma Beam Cover
Plasma Beam covers are green and can be destroyed by a single shot from the Plasma Beam.
Wave Beam Cover
Wave Beam covers are purple in color and can be removed by firing a single shot from Samus' Wave Beam.
Every Type of Block in Metroid Dread
Beam Block
Beam blocks feature a large white circle on them and can be destroyed using any kind of arm cannon shot, bomb, or missile.
Missile Block
Missile blocks feature a large red circle with a black missile design in the center and can be destroyed with either a regular or super missile.
Bomb Block
Bomb blocks feature a large pink circle on them and can be destroyed by using any of the three types of Morph Ball bomb.
Grapple Beam Block
Grapple Beam blocks are grey with a glowing blue triangle on them. Players can pull them out of walls using the Grapple Beam.
Speed Booster Block
Speed Booster blocks feature an orange circle with a black arrow facing to the right. Players can run straight through them while the Speed Booster is active or use Samus' Shinespark ability to destroy them while in either regular or ball form.
Screw Attack Block
Screw Attack blocks feature a blue circle with a black lightning bolt on them and can be destroyed by jumping into them after obtaining the Screw Attack upgrade.
Power Bomb Block
Power Bomb blocks feature an orange circle with a picture of a black Power Bomb in the center and, as the name suggests, can only be destroyed by detonating a Power Bomb somewhere nearby.
Bio Block
Bio blocks are pink and red in color and are made up of what appears to be some sort of living tissue. Shooting them will cause them to explode, which will usually grant access to secret areas. Once players have the Diffusion Beam, they'll be able to use charged shots to destroy them through thin walls. With the Wave Beam, they'll be able to shoot them through any wall or structure, no matter the thickness.
Pitfall Block
Pitfall blocks are generally the one type of block that players don't want to destroy in Metroid Dread. Simply making contact with them will cause them to erode, though players can use the momentum generated from a Cross Bomb explosion or the Speed Booster to safely get across them without falling.
