How co-op works
Online cooperative survival horror for one to four players. Teams investigate abnormal activities across multiple locations, coordinating to locate threats, manage limited supplies, and keep every member alive through each session.
About this game
Sepium sends up to four investigators into locations gripped by paranormal disturbances. Each mission centers on identifying the nature of the threat, documenting evidence, and surviving encounters that intensify as the investigation unfolds. Solo play is supported, but the survival horror structure rewards cooperative communication and shared decision-making.

Resource scarcity defines every choice. Ammunition, medical supplies, and equipment are limited, forcing the group to weigh risk against reward as they explore dark interiors and respond to escalating anomalies. Communication becomes critical when threats emerge, members separate to cover ground, or supplies dwindle and the team must decide who carries what.
Each location presents a distinct investigation with its own abnormal phenomena, encouraging repeat runs as crews master new environments and refine coordination. The blend of evidence-gathering and survival pressure rewards groups who share information quickly and adapt roles on the fly, making every session a test of both nerve and teamwork.

How important is voice communication for co-op play?
Communication is critical in Sepium. You'll need to coordinate when splitting up to cover ground, share evidence findings, decide who carries limited supplies, and warn teammates when threats emerge. The game rewards groups who communicate quickly and clearly.
Are resources shared between players or does each person have their own?
Resources like ammunition, medical supplies, and equipment are scarce and limited across the team. You'll need to make tough cooperative decisions about who carries what and when to use supplies, as there isn't enough for everyone to stock up individually.
