Prepare a collectible run

Use the mission-select collectible count as your baseline and keep a simple mission-by-mission record. Avoid mixing Campaign Remix and standard routes unless the guide explicitly names the mode.

  1. Finish a normal first playthrough if you want to avoid environment spoilers.
  2. Record the mode, mission, rally point, and difficulty for each find.
  3. Capture a landmark screenshot before picking up a Skull.
  4. Return to mission select and verify the collectible count changed.

Handle Skulls in co-op

Collected Skulls are among the items Halo Support says can sync. Available Skull selections are controlled by the fireteam leader's campaign progress.

  1. Choose the player with the most complete Skull collection as leader.
  2. Confirm enabled modifiers in the lobby before launching.
  3. After collection, finish the encounter or reach a reliable save point before leaving.

Verify location guides

A useful location guide identifies the exact mission variant, rally point, difficulty requirements, and a recognizable approach path. A cropped pickup image alone is not enough to reproduce the route.

  1. Prefer routes recorded after the July 28, 2026 release build.
  2. Compare the guide's mission and mode with your own selection.
  3. Check official patch notes when an object or jump route no longer matches.

Before a LASO run

LASO combines Legendary difficulty with Skull modifiers. Test modifier interactions on a short encounter first, then use a dedicated save and a stable co-op group if you plan a full run.
