Marathon Perimeter Data Wall Upper Level Key — Location Guide

The Marathon Perimeter Data Wall Upper Level Key is a locked key door on Perimeter.

This guide covers the exact Data Wall Upper Level Key room location, the fastest route once you are inside Data Wall, and what to expect before opening.

Before You Open

These basics prevent most wasted key attempts:

  • Do not open immediately on arrival. Clear nearby angles first.
  • If the area is contested and you are sure a team is holding it, do not risk the key. Rotate and come back later.
  • If you are opening, try to do it when your route is stable and the space around the door is quiet.
  • For key runs, go in light: mostly empty inventory and basic kit only (for example the free Sponsored Package).
  • Treat the room as a fast hit. Grab priority loot and move out instead of staying too long.

Running light on key attempts reduces downside if you die and gives you more room for high-value loot if the room pays out.

In Marathon, loot quality is tied to both your current rank and map threat level. Perimeter is Threat Level: Low, so its key rooms are usually lower on average than Dire Marsh key rooms, since Dire Marsh is Threat Level: Medium. But RNG still decides single runs, so Perimeter key rooms are not bad by default.

How to Get the Key

The Data Wall Upper Level Key is a rare random drop.

Keys can appear in multiple rarities, including Enhanced, Deluxe, Superior, and Prestige. Higher rarity can improve average outcomes, but no single run is guaranteed.

You can acquire keys through normal raid flow while looting:

  • interior loot points and searchable containers
  • utility storage and bags
  • enemy runners in PvP

If your progression is getting stuck behind RNG, skip the slow loop and push outcomes directly with our Marathon boosting services. We cover Shell tuning, account and faction progression, ranked climb, and custom progression milestones. Tell us your target in live chat and we will build the route around it.

There is no guaranteed loop for this exact key right now. More searches over more runs is still the consistent method.

Simple rule: this key can still be worth opening, but no single run is guaranteed.

Key Room Location

The Perimeter Data Wall Upper Level Key door location is on the far west edge of Data Wall.

Do not confuse this with East Wall. They are different areas. Some players call this side west wall, but that is just a callout, not an official in-game area name.
