Thalassa: Edge of the Abyss

I have a soft spot for games that ask you to grieve alongside strangers, and Thalassa: Edge of the Abyss does exactly that with a quiet confidence that most narrative games spend years trying to find. You play as Cam, a diver who returns to the sunken wreck of the SS Thalassa - a salvage ship set in 1905 - after losing your crew to a mysterious disaster you narrowly avoided. What follows is roughly eight hours of first-person investigation: combing waterlogged corridors, picking up diaries, photographs, financial ledgers, and wax cylinder recordings, then connecting those clues on a dedicated mysteries board to piece together who these people were and what unraveled them. It sits in the same lineage as Return of the Obra Dinn, though far less punishing. Where Obra Dinn demands cold logic, Thalassa cares more about the emotional texture of its characters - the inexperienced chief engineer Thomas, the reclusive captain Hans, the ambitious ship-owner Isabel - than about catching you out. The ship itself is the game's single greatest achievement. Each deck is designed with the kind of structural honesty you rarely see: engineering tight and grimy at the bottom, crew quarters personalized and worn, the captain's bridge sitting quietly atop everything like a sealed confessional. Fish drift past open portholes. Furniture floats. The ambient creaking of the hull under ocean pressure does more atmospheric heavy lifting than most horror games manage with a full sound budget. Your support contact Bailey speaks to you from the surface - and the moments when the signal cuts out as you descend deeper are more unsettling than any jump scare. Sarepta Studio, a small Norwegian outfit, spent six years on this, and you can feel that care in the rendering of every cabin. The friction is real, though, and worth naming clearly. Movement is slow - deliberately so, the devs would argue, and they're not entirely wrong, but there are stretches where backtracking between locked-off sections of the ship tips from atmospheric to tedious. The mysteries board can stall you out even when you've logically solved something, because the game requires a specific evidence combination rather than accepting the deduction you've already made. Listening to wax cylinders locks Cam completely in place, which is a strange choice for a game that already moves at a deliberate pace. Some audio inconsistencies surfaced at launch too, with voices occasionally dropping in volume mid-scene. None of this is fatal. The story's emotional core - grief processed through investigation, loss examined from multiple angles across a single crew - keeps pulling you forward. The back half of the narrative earns the slow burn of the opening. The audience here is narrow but well-served. If you came for puzzles with teeth, look elsewhere. If you want combat or systems to optimize, this is the wrong ship entirely. But for players who finish What Remains of Edith Finch and immediately want something with a deduction layer on top of the same emotional register, Thalassa fills that gap with genuine craft. Steam users have been consistently warm on it, which tracks - this is the kind of game that finds its people and stays with them.
