Grounded Story Walkthrough

Grounded's story unfolds through six major labs, each guarded by unique bosses and full of puzzles. The main quest takes approximately 30 hours, with 60+ hours for 100% completion including optional bosses. This guide provides a complete walkthrough from the opening cutscene to the final machine repair.

Story Walkthrough Tips

  1. Scan every lab item — Each lab has 15–20 scannable items. Scanning gives Raw Science + lore progress.
  2. Read all PDAs — Lab PDAs contain story context (what happened to the scientists, how the shrinking happened).
  3. BURG.L quests — After each Super Chip, BURG.L offers new quests. Do them for Raw Science.
  4. Don't skip optional bosses — The Wasp Queen drops the best ranged weapon. The Orchid Mantis drops the best stealth armor.
  5. Lab shortcuts — Each lab has a shortcut that opens after completing it (connects back to the yard surface).
  6. Boss summoning items — Some bosses (Broodmother, Wasp Queen) require summoned items crafted from specific bug parts.
  7. Build a lab outpost — Place a base with a respawn point near each lab entrance before attempting it.
  8. Bedrolls save progress — Save before each boss fight. Dying sends you back to your last bedroll.
  9. Multiplayer scaling — Bosses scale HP +50% per additional player. Don't bring extra players unless they're geared.
  10. Gliders save time — Between labs, use the web glider from the oak tree to navigate the yard quickly.
