The Secret Project

Site 2 engineers knew they were in desperate circumstances when the kett became aware of their attempts to settle. Engineers tried to research technology that could help them fight the kett.

Acquisition
In Site 1: Promise, there is a datapad that can be found in the lower floor of the building near the Tempest. Examining it will begin the mission.

Search Site 2 for the secret research project
Head to Site 2: Resilience near the lake. The failed outpost was a victim of a kett attack that wiped out most of the colonists stationed there. A recreation of a conversation between two colonists can be found in the second story of the main building. Examining the only available door on the first floor reveals that it was locked from the outside.

Entering the building, a power terminal in the second room can be activated. Upon activation, SAM informs the Pathfinder that a bulletin was released at the time of shutdown; it simply said "Run." The locked door opens, revealing a fiend, while a kett dropship approaches the site.

Defeat the kett
Fight off the kett and the released fiend. Another kett dropship approaches soon after the first, so be prepared.

Once the kett have been cleared, you can continue to search Site 2 for the secret research project. Through one of the now-opened doors, a console can be interacted with to reveal that the secret project was building something to fight the kett with. The project could be finished, with the right components.

Recover components
Three components must be found; you automatically begin with one. The second component can be found just a few steps away in the next room. The last component requires a bit of a drive around the lake to a crashed Initiative shuttle.

Scan the research project
With all of the components collected, return to Site 2. Near the console that you interacted with before, scan an Adapted Initiative Core Tech to complete the mission. You receive +270XP and 100.
