Heart of Darkness is a complete Cinematic Scenario for the ALIEN roleplaying game. 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. This boxed set contains:

• The main Heart of Darkness scenario book.
• A huge double-sided map (format 864x558mm) of the Erebos plasma trawling space station.
• Seven pre-generated characters to choose from.
• Custom cards for secret messages and personal agendas.
• Player maps and handouts.
