Cleanup plan

Clean up safely before quitting.

Most collectible pages show locations; this plan covers the part that causes lost progress and replay time.

  1. Reach a checkpointAfter collecting a Skull or Terminal, continue until the next reliable checkpoint before quitting or changing platforms.
  2. Use mission selectMissed pickups can be cleaned up later. Choose New Game in the relevant campaign mode, select the mission and nearest available rally point, then follow only the remaining entries.
  3. Track by nameIf the game menu does not show a chapter-by-chapter tracker, compare the collectible names on this page with the names already unlocked in your profile.
  4. Confirm co-op creditIn co-op, have the progression owner lead the fireteam and verify the pickup registers before leaving the session.
