SSO: First Captain

From the publisher:

Any long range mission into deep space requires careful psychological testing of all crew, the pressures of enforced isolation and constant proximity can drive people to terrible acts of violence.

Not all testing is perfect.

The first Challenge Deck expansion for SSO, First Captain, tells the story of the Omega's original captain trying to wipe out your rescue team. He does this by a cat and mouse assault on the crew's morale along with a more direct assault on the bodies of anyone who spends too long alone in the ship, picking off lone crew members.

Crew can buddy up to cover each other's backs and lessen the effects of Morale loss while trying to recover their nerve, but in the end desperate times call for desperate measures and a homicidal maniac on the loose certainly qualifies.

This is an expansion. It cannot be played without the SSO: Base Game.
