Marathon Outpost Map Guide: Best High-Tier Loot & Vault Locations

The Outpost Map in Marathon is a high-security UESC Facility that trades the open fields of Perimeter for verticality and close-quarters combat. If you want to succeed here, you need to understand how the maps work and their keycard system that gives access to the best loot. To help you succeed in your extractions, here's a map guide for Outpost.

Outpost Map Overview in Marathon

Outpost has an access requirement. You need to be at least Runner Level 12. While playing on the map, there are usually 3 to 4 squads roaming.
