Blue Door: Difference between revisions

A '''Blue Door''' is a type of [[Door]] from the ''[[Metroid (series)|Metroid]]'' and ''[[Metroid Prime (series)|Metroid Prime]]'' series. They appear in every ''Metroid'' game except ''[[Metroid II: Return of Samus]]'' and are the most common door, requiring no special weaponry to open; a single blast from [[Samus Aran|Samus]]' [[Arm Cannon|arm cannon]] will suffice. They are commonly placed between passages in order to block unwarranted company. In [[Metroid: Other M]], Blue Doors are replaced by doors which open automatically whenever Samus nears them.
