Marathon Data Reconstruction 2 contract walkthrough
The contract can be broken down into the following parts.
- Download harvest logs from Algae Ponds
- Hack three Data Repositories in AI Uplink
How to download harvest logs from Algae Ponds

Since the Algae Ponds is a named location, finding it won’t be difficult. The building has a bright cyan coating, so it’s pretty easy to spot. Once you go inside, go to the second floor.

Take the stairs to go to the second floor and head to the room with a massive glass display. There, you’ll find the terminal. Interact with the terminal to download the harvest logs, which completes the first task.
How to hack three Data Repositories in AI Uplink

To complete the second task, you’ll need to find three Data Repositories in the AI Uplink location. They’re located on the catwalk. You can approach from either the western side or the eastern side. I will strongly advise going in from the east because the western part has a bunch of UESC patrol enemies.

Once you reach the catwalk, you’ll find the three repositories along the path. These are small terminal units attached to the structures. Interact with them to complete the hacking process, and do these for all three repositories. Finishing the second task will also complete the second Data Reconstruction contract.
