You get 10 shards for clearing Fort Iron Pass in A Dusty Trip.

That reward is described in multiple guides covering the Fort Iron Pass run, which say you need to reach about 35,000 m, defeat the mutants, and complete the trial to claim the shards.

Quick Scoop

  • Fort Iron Pass reward: 10 shards.
  • Usual requirement: reach the pass, clear the mutants, and finish the run.
  • Other shard sources mentioned in the same guides: daily quests and, in some cases, buying with Robux.

Extra context

The sources suggest Fort Iron Pass is a slower but repeatable way to farm shards, while daily quests are the faster steady source. One video even notes earning 15 shards total from quests, which helps show why the 10-shard Fort Iron Pass reward matters.
