The Selection Pressures 1 contract in Marathon takes you on a tour of the Dire Marsh map, and you’ll have to take the offensive to the UESC.
In this contract, there are three different tasks. You’ll be playing in the Dire Marsh map and visiting at least two different locations. Let’s look at how to complete the contract as quickly as possible.
Marathon Selection Pressures 1 contract walkthrough
The Selection Pressures 1 contract can be broken down into the following parts.
- Acquire Command Module from Commander in AI Uplink Basement
- Decrypt the Module in building on western side of the Anomaly
- Deliver Decrypted Command Module to DCON
How to acquire Command Module from Commander in AI Uplink Basement
The first task is to acquire the Command Module from the remains of a Commander. You’ll find the remains in the AI Uplink’s basement. Reach the marked spot, and you’ll find the entrance to the building (one-storeyed) that takes you down to the basement.

Keep going straight until you come across the point shown in the image above. Take the left door and keep going straight once again.

From the point above, take the doorway going left. You’ll ultimately reach a point where there’s a locked door in front of you, and the corridor continues on the left. Keep following the corridor, and you’ll ultimately reach the room from which you can salvage the Command Module.

How to decrypt the Module in building on western side of Anomaly

Next, head to the Anomaly POI, and you’ll find an isolated building at the marked spot. Head inside the building, and you’ll find the terminal highlighted by a quest marker. Interact with the terminal to decrypt the module and complete the second task.
Deliver Decrypted Command Module to DCON

To finish the last task, access any of the three DCONs that can be found on the Dire Marsh map. Add the item to its inventory, and wait for the DCON to send back the item. This will complete the final task and the Selection Pressures Part 1 contract.
