Altarium is a first-person, asymmetric PVP Co-Op horror game that can be played by 1-5 players together. Players can choose to play as either the victim or the evil character. Get ready, choose your role, shape your destiny, and survive!


Dr. William, who is a slave to the desire for power, sends a research team consisting of Hannah Falkenhorst, Black Jack Kane, Grimroot, and Marco Rocio to the town of Golden Horn to obtain the Korion Jewel, which gives mystical powers to its owner. It doesn't take long for the research team, who are unaware of the powers of Korion, to realize that they are trapped in Goldenhorn. The guardian of the jewel with mystical powers has no intention of sending the team back alive.
In this exciting adventure where the roles of hunter and prey are reversed, join the team of bounty hunters and try to survive through cooperation, or direct the jewel guardian and defeat the bounty hunters.
To win this challenge, take on the role of good or evil, take control of your destiny, and survive no matter what!


Altarium is a deeply atmospheric horror game that can be played in both PvP and Co-Op modes, accommodating 1 to 5 players. You have the freedom to play as a member of Team A, where cooperation and communication are key to survival, or step into the shoes of Luxazul, the menacing character whose very presence instills fear in others.

In this chilling world, every game is a battle for survival or domination, where the stakes are high and the tension never lets up. With its haunting environments, intricate gameplay mechanics, and intense multiplayer modes, Altarium offers an unforgettable horror experience that will keep you and your friends on the edge of your seats.



Determine your strategy by using all the tools necessary to survive. Succeed in the challenge by using special character abilities, teamwork, and environmental advantages. Try to get ahead in the struggle for survival with the unique abilities and special equipment of your avatar. Survive as Team A or don't let anyone escape as Luxazul!


We are excited to announce that Altarium will be supported with regular updates and will constantly offer players new content. Each update will be carefully prepared with the aim of adding new excitement for you. These updates, filled with brand new content, characters, maps, and equipment, will continuously enrich your gaming experience.
