Game information
Blue Mounted Guns are placed in walls and on the ceiling, firing down green bullet clusters. These clusters will deplete one bar from Takeshi's health, but not harm other enemies. These Guns are indestructible and may sometime appear in groups. They appear commonly throughout levels Final Ninja, and multiple times in some levels. They are placed mainly to make it difficult for Takeshi to traverse areas, requiring him to stop frequently yo avoid damage.

Wall Mounted Guns are also used on Defense Robot Alpha and Defense Robot Zero. Defense Robot Alpha has located in the middle of its body, close to the ground. It can rotate 360°, allowing the brute to fire it at Takeshi wherever he is.

Defense Robot Zero has the Wall Mounted Gun in the same place as Alpha, and it also acts the same. Laser Guards also have the cannon of a Blue Wall Mounted Gun, which will can fire green bullets and also projects a Pink Laser.
