Nobel Award-winning scientists and their revolutionary discoveries have vanished. This ripple in reality is a loss for humanity, and it must be restored. In Machinations through Time, a unique 78-card scenario for Arkham Horror: The Card Game, investigators travel through the past, present, and future to repair the broken timeline, while the minions of Tindalos hound them relentlessly.

This scenario can be played with 1–4 investigators as a standalone scenario, or inserted into a campaign as a side-story. With three copies, it can also be played with 3–12 investigators in Epic Multiplayer Mode.
