Marathon Order/Chaos Contract Guide: How to Trigger Alarms and Download Data
Contracts are one of the primary ways to progress in Marathon, unlocking new gear, materials, and rewards. After finishing the introductory missions for the Mida faction, players receive a contract called Order/Chaos from Gantry.
This mission takes place on the Dire Marsh map and requires players to complete three objectives in a single run. If you leave the match before finishing all steps, the contract resets and must be attempted again.
The objectives can be confusing because the game doesn’t mark exact locations during the match. Instead, the contract descriptions give hints about where to go.
This guide explains how to trigger the alarm in South Complex, defeat the Security Commander, and download the encrypted data in South Maintenance, allowing you to finish the Order/Chaos contract efficiently.

Understanding the Order/Chaos Contract

The contract consists of three tasks:
-
Trigger an alarm in the South Complex
-
Defeat the Security Commander and collect credentials
-
Download encrypted data from a terminal in South Maintenance
All steps must be completed within the same match.
Because the objectives are located across different sections of the map, planning your route and avoiding unnecessary fights will help you finish the contract faster.
Some players use a marathon boost service to speed up contract completion and faction progression when tackling multiple objectives across dangerous zones.
Step 1: Trigger the Alarm in South Complex
Your first objective is located in the Complex point of interest on the Dire Marsh map.
How to Find the Correct Building
After spawning:
-
Open your map.
-
Place a marker on Complex.
-
Travel toward the southern portion of the Complex area.
Look for a yellow building labeled NuCaloric Agriculture. This structure contains the terminal required for the objective.
Triggering the Alarm
Inside the building, locate a red workstation terminal.
To complete the step:
-
Approach the terminal.
-
Interact with it to begin hacking.
-
Wait for the hacking animation to complete.
The process only takes a few seconds, but it leaves you completely vulnerable.
Safety Tips
Before hacking:
-
Clear nearby enemies
-
Watch entrances for other players
-
Ask teammates to guard doors if playing in Trios
Completing the hack triggers the alarm and immediately begins the next phase of the contract.
Step 2: Defeat the Security Commander
After the alarm is triggered, an enemy reinforcement drop arrives.
An aircraft appears nearby and deploys several enemies.
These include:
-
Two regular UESC soldiers
-
One Security Commander
Your goal is to defeat the Commander.
Why This Fight Is Dangerous
The Security Commander is tougher than standard enemies and often arrives while other players are nearby attempting the same contract.
This means you might face:
-
AI enemies
-
Rival players
-
Both at the same time
How to Complete the Objective
-
Focus on eliminating the regular soldiers first.
-
Engage the Security Commander.
-
Loot the Credentials dropped by the Commander.
Once you pick up the credentials, the second objective is complete.
Using abilities from your Runner Shell can make this fight easier, especially if multiple enemies are present.
Step 3: Download Data in South Maintenance
The final step requires traveling to another location on the map.
Your destination is South Maintenance, located in the southwest corner of Dire Marsh.
Reaching South Maintenance
This is often the longest part of the mission.
To travel safely:
-
Move along the southern edge of the map
-
Avoid heavily contested areas
-
Stay alert for enemy Runners
Since many players are completing the same contract, Maintenance can sometimes be a hotspot.
Finding the Terminal
Once you arrive at the Maintenance building:
-
Move toward the southern side of the structure.
-
Look for a small bench with a computer terminal placed on top.
Downloading the Data
Interact with the terminal to begin downloading the encrypted data.
The process completes quickly and finishes the final objective of the contract.
At this point, the Order/Chaos contract is considered complete.
Do You Need to Extract?
Extraction is not required for the contract itself.
Once the objectives are finished, you can safely leave the match and still receive credit for completion.
However, extracting can provide additional rewards such as:
-
XP
-
Materials
-
Extra loot
If you decide to extract:
-
Open your map
-
Locate an Exfil point
-
Travel to the extraction zone
Successfully extracting can make the run even more profitable.
Rewards for Completing Order/Chaos
After returning to Gantry and turning in the contract, you receive several rewards.
Typical rewards include:
-
Random Enhanced Equipment
-
Random Equipment
-
Random Crafting Materials
-
1500 Credits
These rewards help players upgrade their gear and progress through the game’s faction systems.
Players who want to accelerate this progression sometimes use Marathon Contracts Boost services to complete multiple missions quickly and unlock high-tier equipment faster.
Tips for Completing the Contract Faster
Because the Order/Chaos contract requires multiple objectives across the map, efficiency is important.
Bring a Sponsored Kit
Using a sponsored kit reduces risk if you get eliminated during the run.
Travel Along Map Edges
The southern edge of the map often has fewer player encounters.
Clear Enemies Before Hacking
The hacking animation leaves you vulnerable, so always secure the area first.
Play With Teammates
Trios can make the contract significantly easier.
Teammates can:
-
Guard entrances during hacks
-
Help defeat the Security Commander
-
Watch for enemy players
Avoid Unnecessary Combat
Your goal is completing objectives, not winning every fight.
If possible, avoid conflict and focus on finishing the mission.
Final Thoughts
The Order/Chaos contract in Marathon can be confusing at first because the objectives are not clearly marked on the map. However, once you understand where each step takes place, completing the mission becomes much easier.
By triggering the alarm in South Complex, defeating the Security Commander, and downloading encrypted data from South Maintenance, you can finish the contract and claim its rewards in a single run.
With proper planning, smart movement across the map, and careful combat decisions, this contract becomes a straightforward mission that helps push your Marathon progression forward.
