SUNK COST is an action horror game set in the Bermuda Triangle, where players form crews of sea explorers tasked with looting abandoned ships before they sink completely. The experience centers on online co-op play for up to six participants on PC, blending tense exploration, heavy object hauling, environmental hazards, and encounters with hostile creatures. Ships appear in three different sizes with fresh layouts each run, forcing teams to adapt quickly as decks tilt, water rises, and valuable cargo shifts on its own.
Gameplay
Teams board drifting vessels and search for sellable items ranging from small pocketable objects like compasses to bulky antiques such as pianos, safes, and wardrobes. Larger pieces require coordinated effort from multiple players to move efficiently, especially when navigating stairs or uneven surfaces. The environment works against the crew as the ship lists progressively, sending furniture sliding and turning passages into slopes. Water floods upward from lower decks, eventually forcing difficult choices about whether to risk swimming for high-value targets.
Creatures inhabit the ships and surrounding waters, appearing at inopportune moments to threaten players. Swimming too far from the extraction boat or barge invites additional dangers from the depths. Voice communication operates on proximity, limiting how far calls for help can travel unless a radio or megaphone has been purchased. Fallen players retain the ability to hear living teammates but can only speak among the dead, creating moments where warnings about sliding hazards go unheard.
Progress ties directly to a quota system managed by the faceless partners. All recovered goods return to a central barge for evaluation, and earnings fund equipment upgrades from the partners' shop. Crews receive three attempts to meet the target before facing consequences. Character customization options allow personalization of explorers before each outing.
Game Modes
The core loop revolves around repeated co-op expeditions to randomly generated ship interiors. Each trip presents a new layout scaled to one of three sizes, emphasizing teamwork in looting and survival under time pressure from the sinking environment. Procedural generation ensures variety across sessions, while the quota mechanic structures runs around collection goals and return trips to the barge.
Proximity-based voice chat integrates directly into gameplay, encouraging close coordination during heavy item transport and monster encounters. No separate competitive or solo modes exist beyond the primary shared experience, keeping focus on group dynamics in the hazardous setting.
Core Mechanics and Progression
Item hauling forms the central activity, with smaller objects fitting easily into pockets and oversized ones demanding patience or assistance to avoid drops on inclines. Certain pieces exhibit unusual behavior when unobserved, adding an extra layer of vigilance. Gear acquired through the partners' shop improves capabilities for future runs, though costs contribute to the ongoing debt pressure.
Environmental changes unfold dynamically during each expedition. Tilting decks alter navigation paths, rising water limits accessible areas, and creature spawns create sudden threats. These systems combine to create high-stakes decisions about risk versus reward when pursuing the most profitable cargo.
Is It Worth Playing?
SUNK COST suits players who enjoy co-op horror experiences that emphasize teamwork, environmental interaction, and resource management over direct combat. The unique combination of tilting ships, moving loot, proximity voice, and quota pressure delivers a distinctive loop for groups seeking tense, repeatable sessions. As an Early Access title with a planned full release in Q1 2027, the current version contains the core systems in playable form, though variety in monsters, layouts, and items remains limited until further updates. Those drawn to procedural co-op adventures with horror elements and strong communication mechanics will find the most value here, particularly if they appreciate games that reward careful coordination and quick adaptation.
