The Overlooked: This is Only a Test

The Overlooked: This is Only a Test is the third and final quest in the The Overlooked side quest line.

Objectives

 * Head to Hyperion mortar
 * Aim mortar at Overlook
 * Fire mortar
 * Aim mortar (after firing it the first time)
 * Fire mortar again

Strategy
Karima wants you to test the shield she buit by firing a mortar at it. Head to the Aggregate Acquisition at the opposite end from Overlook to reach the mortar controls, and fight off Hyperion forces on the way there.

Once you've reached the mortar controls, Karima will tell you to align the mortar cannon. Do so, and she'll tell you to fire. Fire the cannon, and you'll see it heading towards Dave's house and dislodging it from the cliff and with Dave plummeting to his death.

After that, she wants you to fire the cannon again, but this time to actually test the shield. Re-align the cannon and fire when she prompts you to, and the test will be successful.
