Eliminate power sources to disable the barriers blocking deeper access into the tunnels.
- Go down the tunnel to the next barrier, a short distance in.
- Just to the right of the barrier you will see what look like 2 metal crates stacked on top of each other.
- These "stacks" are generators powering the barrier.
- You will be prompted to shoot and destroy the generator.
- This will start a timer on you before an alarm sounds.
- The first time it will be a 30 second timer.
- Go through the barrier as soon as it drops.
- You will need to fight through a number of Legionaries.
- Beyond them, you will encounter another barrier.
- The second generator is, again, to the right of the blocked archway.
- Destroying this generator will reset the timer and bring it up to 40 seconds.
- Once again, run through the shield as soon as it drops.
- This time you will be facing Phalanx and Psions.
- Defeat those in front of you, taking the first right you can.
- Go up the ramp to the back portion of the hallway.
- In the back right of this hallway, you will find the next generator for you to deal with.
- Shoot it and return to the main path forward, where the barrier is fading.
- Destroying this generator will reset the timer to 50 seconds.
- Run along the main hallway, continuing forward.
- You will see Incendior and a Centurion ahead of you.
- Defeat the pair and look toward the barrier.
- To the right of that you will find the next generator you need to destroy.
- This will reset the timer to 1 minute.
- You need to find and destroy the last generator.
- Go forward past the now-down barrier.
- In front of you are Psions and a Phalanx.
- Go down the hallway to the left.
- On the left-hand side you will see the final Shield Battery.
- Destroy it to bring down the barrier that is blocking your access to the final chamber.
- If the alarm goes off, you will fail the adventure?
