The Dexter alternate reality game was a transmedia experience that entailed Dexter fans joining a crowdsourced investigation team led by the "Serial Huntress," to hunt a Serial Killer in the real world —“The Infinity Killer.”
For 8 weeks players across the world collaborated to discover online and real-world clues, and to solve the Infinity Killer’s dark puzzles. The game led them through all kinds of plot twists and turns, but ultimately players achieved their goal: Justice.
