How to complete Order/Chaos in Marathon

After smashing glass to appease MIDA in Marathon, the rebellious Gantry will give you the Order/Chaos priority contract. Staying on theme with the faction, you're sticking it to the UESC by triggering alarms and hacking into encrypted data across Dire Marsh. It's easier said than done: you have three objectives to complete in a single run that send you from one side of Dire Marsh to the other.

Begin by heading to the south end of Complex in the east of Dire Marsh, where you'll find a red terminal inside a yellow NuCaloric lab near the centre of the POI. The terminal sits on the eastern edge overlooking the swamp, so reach it by sticking to the outskirts of Complex—I recommend this given how dangerous the area is.

Interact with that terminal and a Security Commander will spawn outside from a red drop-ship, along with reinforcements. Kill the Commander and collect its credentials from the ground; the quest item appears as a yellow icon, as with previous quests. Finally, download data from a terminal in the south of Maintenance.
