Fast answer

Current 0.5 guide consensus says the Abyss gate requires all three Diving Suit pieces equipped together. Recipes are tied to Aquatic Optical Disks; cross-checks report 4,500 Raw Science and 9 Quartz Glass for the set, so verify those values in your current Science Shop.

Do this first

Save-safe order

  1. Reach the Pond progression that introduces the Diving Deck.
  2. Collect the Aquatic Optical Disks for the three suit recipes.
  3. Verify current Science Shop costs and materials.
  4. Craft and equip helmet, chestplate, and boots together.
  5. Return to the gate and recheck all three equipped slots.

01

The equipment gate

Better oxygen alone is not the same as the full set requirement. Current specialist guides agree that the complete equipped Diving Suit is the progression check for the Diving Deck.

02

Plan before farming

Treat the route as three recipe unlocks plus one shared material plan. Check each recipe in the current build before collecting a large amount because Grounded 2 is still in Early Access.

  • Aquatic Optical Disk prerequisites
  • Raw Science costs
  • Quartz Glass chain
  • All three armor slots
  • Gate recheck

03

If the gate still rejects you

Confirm all pieces are the Diving Suit set—not starter diving gear—and compare build numbers in co-op. Do not delete quest or save data to force the gate.
