About
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.

6/10 at its best currently, I usuallu enjoy all of the chaser games, this game should have been tagged as early access but overall for its price It has quite a bit of things to like. It still feel like it is early phases of it release.
Soberana caquita. No lo compren, enserio, no lo compren
Nunca escribo reseñas, pero este juego se la merece, 0.4h de juego. 16 gb de ram, un ryzen 7, y una grafica rtx 3050, literalmente en graficos al mínimo y no se puede jugar. No rembolsee el juego por que tuve fe de que lo arreglasen en un futuro, aun no lo probaré, le daré mas tiempo de margen, ya que me pareció lamentable. ACTUALIZACIÓN: 18/7/2025, pruebo a ver si lo han arreglado, busco lobby, no hay ni uno solo Xd El juego está muertísimo.

Great game! Good graphics, good game play. A lot to learn at first but easy enough to pick up and learn. Can't wait to see how it all develops!!
Alterium delivers a chilling experience with stunning graphics that truly immerse you in its eerie atmosphere. The gameplay is a perfect blend of suspense and strategy, making it an absolute blast when played with friends. Each session is packed with unexpected twists, keeping everyone on their toes and heightening the thrill. If you're looking for a game that combines horror and fun, Alterium is a must-play!
Bu oyun kesinlikle gerilim ve heyecan severler için mükemmel bir deneyim! Hem kötü adam hem de iyi adam olarak oynama imkânı, oyuna inanılmaz bir derinlik katıyor. Korku ve adrenalin dolu atmosferi, beklenmedik olay örgüsü ve harika ses efektleriyle her saniye daha fazla içine çekiyor. Hangi tarafta olduğunuz fark etmeksizin, hikâyenin her iki tarafından yaşanan deneyimler sizi ekrana bağlıyor. Şimdiye kadar oynadığım en sürükleyici korku oyunu olduğunu rahatlıkla söyleyebilirim! Kesinlikle kaçırılmaması gereken bir başyapıt! Emeği geçen herkese teşekkürler.
The gameplay was really enjoyable, and the graphics were quite impressive. I had a fantastic time with my friends; you can confidently get it and play with your friends.
Oyunun atmosferi çok iyi. Arkadaşlarla oynarken çok keyif aldık. Ayrıca oyunda Kötü ruh olarak ta oynayabilmek çok eğlenceli ve gün geçtikçe de geliştiriliyor. Geliştirilecek birkaç yeri var tabi ama eminim yakın zamanda kusursuz olacaktır. grup olarak opynandığında ayrı bir güzel tabi :) Geliştirici ekibe başarılarının devamını dilerim.
Wo bleibt das Marketing? Die Idee ist total spannend und ich hätte es gerne behalten, jedoch findet man keine Lobby. Ich habe der Suche zweimal jeweils 25 Minuten gegeben um in eine Lobby zu kommen, doch keine Chance. Pushed das Spiel und ich komme garantiert wieder! Ps. Ich habe mehrfach gelesen, dass man nicht verstünde was man als Überlebender eigentlich machen soll. Hier hilft es zu lesen. Direkt am Anfang bekommt man ein Tutorial wo alles erklärt wird.
With more updates and levels, Altarium will be worth picking up. I see promise but there's not enough players and content yet
