Alterum description
Alterum — Survival and Suspicion in an Otherworldly Facility
In Alterum, a group of brave explorers returns to a site only to encounter something inexplicable: some crew members are possessed by restless souls. Those who were recently loyal teammates have become altered. The game supports 4–8 players and centers on survival, deduction, and a tense battle of wits to uncover who among you is no longer human.
What you do
- Observe: Listen to how others speak, react to events, and behave in critical moments. Inconsistencies are clues worth noting.
- Unite: Discuss, persuade, and search for lies in words and behavior. One wrong choice can tip the balance in the altered’s favor.
- Explore: Search for ancient spells, collect items, activate mechanisms, and decipher signs. Hurry to prepare for the encroaching darkness.
- Use your voice: Read spells aloud from the spellbook and scrolls. Spells can open doors, trigger traps, or temporarily weaken the possessed—yet they can also backfire.
- Exorcise: When suspicions mount, exorcise the possessed. The more like-minded allies you have, the higher your chance of success.
Roles and dynamics
- Explorers seek to survive and identify the altered among them, coordinating to exorcise the threat.
- Possessed cultists inhabit a loyal explorer’s body with a hidden, dangerous agenda: destroy those who disturbed your peace. Disguise yourself, perform tasks, read spells, and participate in discussions to blend in and avoid suspicion.
- Manipulation is key—convince others to exorcise loyal allies, plant false clues, and become the explorers’ best friend to steer outcomes in your favor.
- Abilities and tools can be activated with the ritual dagger and cultist spells. Use sabotages, appearances, and sensory impairments to unsettle the group.
- Self-sacrifice is an option for the altered: sacrifice your own blood to unleash or empower dark abilities, but it risks revealing your true nature and breaking the group’s trust.
Alterum blends social deduction with exploration-driven puzzle-solving. Gather allies, read the room, and balance trust against fear as you race toward dawn—either to root out the possessed or to shepherd an impossible darkness back into silence.
