Heart of Darkness is a complete Cinematic Scenario for the ALIEN roleplaying game, written by sci-fi novelist Andrew E.C. Gaska. It is a stand-alone adventure, but also serves as a conclusion to the Draconis Strain Saga begun in the cinematic scenario Chariot of the Gods and continued in Destroyer of Worlds. The scenario is designed for 3–5 players plus the Game Mother, and is a spiraling descent into soul-crushing madness.

• A huge double-sided map (format 864x558mm).
• Seven pre-generated characters to choose from.
• Custom cards for secret messages and personal agendas.
• Player maps and handouts.

The ALIEN RPG core rulebook OR the ALIEN RPG Starter Set is required to play.
