The Sinking City 2 achievements: Step-by-Step Guide

The Sinking City 2 achievements are divided between story progression, weapon unlocks, investigations, exploration, and full-completion objectives. The verified list contains 23 achievements with a combined value of 1,000 Gamerscore. Several objectives should unlock naturally while advancing through the campaign, while others ask you to investigate optional subjects or collect specific forms of evidence.

The most important planning detail is that some achievements explicitly require progress within one playthrough. These include listening to every Mushroom Jack broadcast, unlocking every Emergency Relief Crate excluding DLC, and reading all writings that were not present before. Treat those requirements as ongoing campaign tasks rather than cleanup targets.

The story achievements are tied to named milestones rather than hidden conditions. Their descriptions point to several major locations and events: Miskatonic University, Akeley Memorial, the Arkham Fish Market, and the ritual connected with “Soulmates.” Because the list does not specify exact chapter names, use the achievement descriptions as checkpoints instead of assuming a fixed mission order.

Weapon achievements are similarly direct. You need to obtain four named weapons: the shotgun, submachine gun, rifle, and grenade launcher. Keep an eye on newly available equipment during normal progression, and check your achievement list after each major weapon acquisition.

Seven achievements focus on investigations. Their wording suggests that each objective is tied to a specific clue chain, location, or unusual subject rather than a general kill count. The safest approach is to investigate suspicious objects and spaces whenever the game presents them, especially when the description mentions a mystery, song, machine, locker, or storage area.

The achievement list does not provide exact room names, chapter numbers, or interaction sequences. For that reason, avoid relying on a rigid route that claims a specific order. Instead, use the target descriptions below as a field checklist and verify each achievement before leaving a major area.

Three achievements require special attention because their descriptions include collection or exploration conditions. Mycophile asks you to listen to every Mushroom Jack broadcast in one playthrough. From Oblivion requires reading all writings that were not there before. Behind Every Crate Man... requires unlocking every Emergency Relief Crate in one playthrough, with DLC excluded.

These objectives are best handled through consistent exploration. The available achievement information does not specify the total number of broadcasts, writings, or qualifying crates, so do not invent a numerical target. Instead, treat every discovered item as part of the same campaign record.

The Talent objective is separate from the three one-playthrough exploration goals, but it belongs on the same planning sheet. What Dreams Are Made Of requires all Talents, so review available progression options regularly rather than waiting until the end of the campaign.

A clean completion route starts with natural story progress, then combines exploration with investigation. Do not rush directly toward the final achievement. The list contains several objectives that can be missed in practice if you leave areas unexplored or fail to track one-playthrough requirements.

For current reference, the achievement list and platform details are available through the The Sinking City 2 achievements listing on TrueAchievements. The listing records 23 achievements worth 1,000 Gamerscore and gives the Xbox release date as August 18, 2026.
