Security Access A is a connecting room in the Phazon Mines. It appears in Metroid Prime. The entry is initially blocked from the Main Quarry by a Dual-Control Force Field, however this can be deactivated via two Interface Modules. There is a Bendezium wall to the left that can be destroyed with a Power Bomb to obtain a Missile Expansion.
