Player steps
Install the current update, prepare a diving suit, healing, food, and storage, then approach the pond from a safe shoreline route. Follow this step before moving to the next objective. It keeps the route focused and avoids unnecessary detours.
Check each equipped weapon in shallow water before a long dive because a recipe or item from the original game is not evidence that it works in Grounded 2. Follow this step before moving to the next objective. It keeps the route focused and avoids unnecessary detours.
Use the current Analyze and crafting entries to record the exact materials shown by your game build instead of copying an old underwater recipe. Follow this step before moving to the next objective. It keeps the route focused and avoids unnecessary detours.
