About this expansion

Arkham Horror: The Card Game – The Boundary Beyond: Mythos Pack is a 1–2 player scenario expansion for Arkham Horror: The Card Game, with an approximately 120-minute play time. It is the second Mythos Pack in The Forgotten Age Cycle.

Your investigation into a strange relic has brought you to Mexico City, but the familiar world soon begins to change. As the architecture shifts into something from a history book, your objective turns from investigation to survival.

The Boundary Beyond continues the story that began with a scientific expedition to ancient Aztec ruins in the rainforests of southern Mexico. After returning home with a priceless artifact and facing a series of urgent objectives in Threads of Fate, you now seek to undo your mistakes—while the choices and sacrifices already made shape the mission ahead.

The fabric of time is unraveling, and the timeline may not be as stable as you believe. Step beyond the boundary, confront the consequences of the expedition, and work to restore history before it is too late.

  • Players: 1–2
  • Play time: approximately 120 minutes

With its Mexico City setting, shifting architecture, and focus on the unstable fabric of time, The Boundary Beyond adds a dramatic chapter to The Forgotten Age. The choices and sacrifices surrounding your investigation continue to influence what comes next as you attempt to survive and set the timeline right.
