| How to Find Kitt | |
|---|---|
| 1 | ![]() Make your way to the large circular building southwest of the Research Center in the Originium Science Park. |
| 2 | ![]() Look for the building's entrance and head inside to enter the Underground Area. |
| 3 | ![]() Kitt is in the large room just before the branching hallway within the Underground Area. |
| 4 | ![]() Kitt is standing near one of the displayed rock formations. Speak to him to start the quest. |

After speaking to Kitt, follow the path inside the facility and destroy the glowing red orb to remove the obstacle. You'll then need to jump through a small laser grid to get to the other side.

Head further into the large room and approach the second table to the left to find the research data. You'll then need to fix the repair logic puzzle.

Arrange the three repair logic pieces like the image above to solve the puzzle and repair the module. You then need to read the research data to collect it and progress the quest.

Head further inside the facility to enter a room with a few laser grids. Turn right from here into another room and approach the table to the right to find the research data. You'll need to fix another repair logic puzzle to retrieve and read the second file.

Arrange the three repair logic pieces like the image above to solve the puzzle, and then read the research data to progress the quest.

Head north through the hallway with a laser grid and quickly run to the left room to avoid getting hit.
The last research data is on a table within this room. Interect and read the file to collect it and progress the quest.

Exit the room north and use one of the boxes to jump over the laser grid, then enter the control room on the right side of the hallway where Harper is located.
Speak to Harper and go through his dialogue and you'll be presented with three options: keep his secret safe, share his data, or give him data related to his research.

We recommend you pick the third option whihc is to give him data related to his research. This resolves his dilemna positively and he'll happily agree to share his data with you.

Although not part of the quest, we recommend you interact with the glowing yellow circuitry in the middle the room where Harper is located.
This is an Orginium Circuitry Component Style that is required for a repair logic puzzle in a later quest called Repair Story.

Exit Harper's room and follow the path right and interact with the switch to open the door leading back outside.
As soon as you head outside, Kitt will contact you on your Baker and you'll automatically submit the research data which also completes the quest.
