The Return on Investment 2 is one of the newer priority contracts in Marathon that will increase your relationship with the Traxus faction.
The contract has two tasks to complete, and let’s look at how to complete both of them without any extra effort.

Marathon Return on Investment 2 contract walkthrough
The Return on Investment 2 contract can be broken down into the two following tasks.
- Acquire explosive supplies from western Maintenance
- Deal explosive damage to UESC or Runners
How to acquire explosive supplies from western Maintenance

The first task will require you to travel to the Maintenance POI. To be more precise, head to the southern part of the POI where all the buildings in white and pink are located. The container you’re looking for is located in the building in the image below.

When you first find the building, it will be locked. To enter the room, shoot boxes around it until the barrier has been disabled. Head inside, and take the ladder. Once you get to the first floor, a quest marker will display the location of the supplies. Loot the supplies, and you’re ready for the second part of the contract.

How to deal explosive damage to UESC or Runners
To complete the second task and the contract, you have to do at least 750 damage with the explosives to either runners or UESC troops. Unless you’re extremely good at PvP, it’s best to target UESC troops. Once you notch up 750 damage, you’ll be able to complete the second Return on Investment contract.
