Drain Diver
“Drain Diver” unlocks when you return the Sewer Queen’s crown. Progress should be completed on a normal save and confirmed by the platform achievement notification. The recommended approach is to explore the sewers, obtain the crown, and return it to the sewer queen. For cumulative goals, avoid switching saves and check the relevant bank balance, collection page, mission chain, or job counter before continuing. Co-op can speed up many objectives, but the player who needs the achievement should perform or receive credit for the final triggering action. If the achievement does not appear, save the game, return to the main menu, reload the same character, and repeat the last valid action. This page uses the current Steam achievement description as the authoritative completion condition; platform trophy names and point values may differ while the gameplay requirement remains equivalent.
Useful tips
- Keep cumulative progress on one save
- Let the target player perform the final trigger in co-op
- Check platform sync only after the game has saved
Platform notes
Core objectives should be available across supported platforms; button prompts and physics can vary by platform and input method.
