Fast answer

Update every co-op player, check the 0.5 issue list, and back up the world. Follow the Pond story until the Diving Suit gate appears, then branch into the suit, Phantom Quartz/Quartz Glass, and Toe Biter Buggy routes as needed.

Do this first

Save-safe order

  1. Confirm the 0.5-era build on every platform in the session.
  2. Back up before a major Early Access progression push.
  3. Follow Pond objectives and scan new materials.
  4. Use the Diving Suit page when the Abyss gate blocks progress.
  5. Use the Quartz and Toe Biter pages for their separate journeys.

01

What Update 0.5 adds

Into the Abyss turns the Pond into a major progression space with underwater exploration and construction, new threats, diving gear, movement systems, and the amphibious Toe Biter Buggy.

  • Pond and deep-water exploration
  • Underwater base building
  • Diving equipment
  • Toe Biter creature and Buggy
  • Ziplines

02

A practical route

Treat the update as linked gates, not one enormous checklist. Establish safe access and oxygen, solve the Diving Suit requirement, collect its material chain, then commit to long Abyss dives.

  • Preparation and backup
  • Pond onboarding
  • Diving equipment
  • Phantom Quartz to Quartz Glass
  • Abyss descent
  • Optional Buggy and zipline expansion

03

Known blocker check

If Diving the Depths does not advance after Eelgrass analysis, check whether Eelgrass was scanned before the quest began. That exact condition is officially tracked.
