Bionic Commando (NES)/Neutral Area 15

This neutral area is just like Neutral Area 13, except midway between the doors, there is a steel wall that is in your way. When you reach it, shoot and it will disappear. This also causes the neutral area guards (in white) to appear and attack. Just shoot or avoid them. In the first door, there is a 1-up and in the second, the essential orange transmitter.
