Quest stages of Mission: Countdown {Missile Silo Location}

1. Head for the Control Room

I should explore {Missile Silo Location} and make my way to its Control Room.

This is the main objective of this mission. You will have to fight through many areas full of robots and turrets. Completing the objectives will open up the laser grids to the next areas and finally you will reach the control room where the launch area is located.

Note: Having hacking skill at level 3 is very helpful here. Each area of the bunker has a terminal that controls local turrets and reprogramming them to attack the robots you'll have to deal with is a great help.

2. Find a way past the Laser Grids

Just inside {Missile Silo Location}, a laser grid blocks the way forward. I need to find a way to bypass the security system.

Find the Security Station Terminal > Security Protocol - Security Station Alpha (Bravo / Charlie).

You now have three minutes to repair all pipes in the main reactor room (if I counted correctly, it is fourteen of them). If you don't manage to do it in time, you will have to shut down the reactor again and start repairing from the beginning.

Pipes will not be marked. Cracks, hissing sound and steam that comes out of them should help you locate them.
