The ultimate weapon of the U.S.S. Discovery is not its phasers or torpedos, but rather its unique propulsion system: the spore drive. Now the Discovery has accidentally travelled into the mirror universe where the previous I.S.S. Discovery has been destroyed. Several members of the I.S.S. Charon would like to take the Discovery to use it for their own aims.

In Star Trek: Discovery – Black Alert, players will divide into teams, and each team represents key members of either the U.S.S. Discovery or I.S.S. Charon crew. Players will take turns activating locations on their ship, navigating through the network, and attempting to accomplish missions. One crew is attempting to return home, while the other wants to capture their ship. Which team will emerge as the victors?
