Area 5 is the fifth stage from Super Aleste.
This stage takes place inside of a planet, with the super Aleste digging underground. It has many narrow passageways and falling rocks which the player must watch out for. At some points in the stage the path is completely blocked, so the player has to wait for a specific enemy to dig through the terrain to open up a path to go through.
Many of the passageways are patrolled by turrets and other enemies, making some weapons more useful than others for this particular stage.
