Supply Caches

The 36 stations by act, how mods and slots get there, and what Quartermaster really asks for.

Supply Caches and Quartermaster

A Supply Cache is a station in the campaign where you restock ammo, swap weapons and fit mods. Weapons you pick up, COG or Locust, are added to what you can equip there. A weapon can carry up to four modifiers. The mods and slots come from Hard Cases and side missions. In Horde Siege caches cost Energy, but they are a separate system.

Two different things. There are 36 cache stations to find in the campaign (the Journal lists them as Supply Caches Found). The achievement Quartermaster is worded by Xbox as “unlock all Supply Cache items in the Campaign”. That is a count of items, not stations, and nobody has published the full item list. Visiting all 36 stations does not prove you have it.

What players report about Quartermaster

  • The achievement shows a percentage. Several players report being stuck at 92% after everything else was done, with the Turret and the Decoy not appearing in the cache.
  • One player says a title in the weapon list read 12 of 13 items, and picking up the Torque Bow they had missed completed it. They say everything should be unlocked by Act 3, Chapter 5, where the Torque Bow first appears. A weapon you have not seen at the cache shows a yellow mark beside its name.
  • Another says replaying Act 2, Chapter 1 on Casual made it unlock during the cutscene into Chapter 2. A third replayed several missions without it unlocking. These are player reports from the first days after launch, not official fixes.

Armor mods seen so far

Twenty armor mod names have been recorded in the campaign, with where creators saw each one awarded. This is a start, not the complete Quartermaster list: weapon mods, tactical gear mods (Injector, Disruptor, Stim Vaporizer, Pulse Drone) and equipment such as grenades and mines are not mapped here, and the full item pool has not been published. Treat the “where” column as a lead, not a guarantee.

How reliable are the stations?

The 36 count and the station list come from one aggregator (e-day.wiki) that links creators’ recordings with timestamps, and Act 2 is cross-checked against PatchCrazy’s walkthrough and Act 3 against the first-hand Gamer Social Club guide. Station descriptions in Act 4 and Act 5 rest on that one list, so they are marked low or medium confidence. Video times are as that list gives them: we have not watched them frame by frame.
