Picture a game where players investigate strange occurrences and piece together that something vast and alien is present. Not a monster to fight. A presence whose existence alone breaks the protagonists mind. The horror is not violence. It is the realization that humanity is irrelevant.

Summer Engine helps you build that growing comprehension through conversation. Describe the cult, the artifact, the entity. The AI helps construct investigation systems, sanity mechanics, and revelation pacing so the player arrives at horror through understanding, not jump scares.

Cosmic horror games work when the player dreads learning more but cannot stop. Every document found, every ritual witnessed, every glimpse of something that should not exist makes the picture clearer and more terrifying. That investigative compulsion is the mechanic you are here to design.

• Writers and designers influenced by Lovecraft, Thomas Ligotti, or Jeff VanderMeer who want to build investigative dread.
• Developers building mystery games who want the resolution to be worse than the question.
• Teams interested in using knowledge itself as a horror mechanic rather than physical threat.
• Fans of Call of Cthulhu, Cultist Simulator, or Sunless Sea who want to build in that tonal space.

• Investigation Horror

  Build a mystery game where gathering information about the entity is the core loop, and each discovery increases dread rather than providing comfort.

• Cult Narrative Game

  Design a story about a community in the grip of something beyond their understanding, told through documents, encounters, and environmental decay.
