This expansion adds unique actions to unlock for each crew member. Use your scientific specialization in tandem with environment-specific comprehension to perform actions unique to your character. Lean on your scientific training to discover how all of this peculiar, newly-acquired comprehension has significance that could keep everyone breathing a bit longer. With the Scientific Specializations module, your "aha!" moments allow you to specialize in ways others cannot—which is a good thing if you all want to survive whatever "this" is and celebrate all of those breaths you've taken for granted. —description from the publisher
