This standalone adventure is a conclusion to the Draconis Strain Saga that started in Chariot of the Gods (see "'ALIEN Roleplaying Game' Supplemental Products"). The new adventure comes as a boxed set that supports three to five players and their Game Mother. It includes maps, cards, handouts, and pre-generated characters, but the ALIEN RPG Core Rulebook or ALIEN Starter Set is required to use this adventure.

ALIEN RPG: Heart of Darkness will retail for $29.99.
