Wrath of the Abyss

From publisher blurb:

What lurks beneath paradise? The newly colonized tropical planet Rearea is a tourist's dream: clear water, white beaches, and most notably, a 5,000 km-long coral reef. When construction for a luxury resort starts damaging the reef, mysterious illnesses and deaths begin. The PCs, investigating the situation along with a brilliant local oceanographer, discover a secret that could spell the end of every human on Rearea. The heroes find their skills put to the test as they try to stop the destruction of the planet, with failure out of the question.

Wrath of the Abyss is a short science fiction adventure for Cepheus Engine and similar RPGs.
