Game description
The year is ~2200. On a remote mining outpost, a mysterious parasite is causing a severe outbreak that is quickly turning into an humanitarian crisis. Reports of violence, madness and mutations have forced the local government to enact a total lockdown of the settlement.
A team of specialists has been dispatched to contain this threat, find out where this organism came from and hopefully reestablish order.
