Alterum

About this game

At their next site, a group of brave explorers encounters something inexplicable: some of them are possessed by restless souls. Those who were recently loyal companions have become something "altered".

Multiplayer for 4–8 players. How well do you know your friends?

You are a explorer trapped in a facility with otherworldly powers. Your task is to survive and uncover who in your group is no longer quite human.

  • Observe. Listen to how others speak, how they react to events, how they behave in critical moments. Any inconsistency is a clue.

  • Unite. Discuss, persuade, search for lies in words and behavior. One wrong choice - and the altered gain the advantage.

  • Explore. Search for ancient spells, collect items, activate mechanisms, and decipher signs. Hurry to prepare for the darkness!

  • Use your voice. Read spells aloud from the spellbook and found scrolls - this can open doors, activate traps, or even temporarily weaken the possessed. But be careful: spells can both help and kill.

  • Exorcise. When enough suspicions have built up - exorcise the possessed. The more like-minded allies you have, the higher the chance of success!

You are the soul of an ancient cultist who has possessed the body of a explorer. Your mission is to destroy all who disturbed your peace!

  • Disguise yourself. Perform tasks, read spells, participate in discussions. Be "one of them" to avoid suspicion.

  • Manipulate. Convince them to exorcise the loyal ones, plant false clues. Become the explorers' best friend.

  • Activate abilities and special spells. Sabotage, change your appearance, deprive them of sight, and much more using the ritual dagger and cultist spells.

  • Self-sacrifice. To use altered's abilities and special spells, offer the blood of your body as a sacrifice to the devil! Try to remain unnoticed - explaining it will be difficult.

Alterum
