Sepium

Sepium is a tense 4-player online co-op survival horror game. Assemble your crew to explore a variety of infested locations, where the world is charged with paranormal activity and constant danger. Investigate eerie environments, confront the weird, and push further to gather precious loot that will extend your chances of surviving another hour.

Your mission is to accomplish assignments, push back hostile forces, and uncover the hidden mysteries of this haunted world. Every step you take is recorded, supervised, and assessed at the end of your deployment, adding a layer of accountability to your teamwork and decisions under pressure.

Prepare for deployment into massive levels designed for teamwork. Each stage features its own atmosphere, hazards, and tricks, challenging you to adapt, improvise, and stay alive. Use a varied set of equipment to complete a rich range of tasks—from scanning for radiation and locating dangerous anomalies to battling bosses and even summoning demons when the moment calls for it. Keep your eyes open for hints scattered through the environment to guide your approach.

Sepium supports up to four players online in co-op, with flexible options to suit how you want to play. Join forces in a server browser to find teammates, or test your limits in a demanding single-player run. You choose how to form your squad, and you’ll need to rely on quick thinking and coordinated action to prevail.

Faced with a hostile world, you will encounter local fauna and unsettling ambience that never leave you alone. Humanoid and non-human threats are everywhere, ready to test your resolve and force you to fight back. Perilous events only raise the stakes, demanding smart tactics, resourceful use of your tools, and careful movement through the environment.

Exploration is paired with loot management: search for items, add them to your inventory, and employ diverse strategies to maximize their effectiveness. Sell what you don’t need and upgrade your gear to push further into the unknown. For players seeking a fresh challenge, Sepium also features procedurally generated levels, ensuring that no two playthroughs feel the same and offering a new remix of threats, layouts, and discoveries with each run.
