Metroid Dread is filled with collectible power-ups, upgrades, secret pathways, and more. Some of these go hand in hand as you will need certain power-ups or weapons to progress through the different areas on the planet ZDR. One of these upgrades is the Storm Missile.
To unlock the Storm Missile, you will need to head to Ferenia. Here you must find and defeat Escue, and you will receive the Storm Missile upgrade as a reward. You can find Escue's boss room on the far right of Ferenia through the bomb blocks.
This ability allows Samus to fire multiple missiles at once and to damage electrical enemies. With the Storm Missile in Samus' arsenal, she can now open the previously locked green doors. To use this upgrade, hold R and aim at each of your targets. A reticle will appear, showing that you have locked. Once all targets are locked, simply fire with Y.
To open the green doors, you must target each of the green switches around them. Once all have been shot, the door will open, and Samus can proceed and go where the player previously could not explore. Storm Missiles can also target multiple enemies and deal massive damage.
