The U.S.S. Discovery has traveled into a mirror universe! You must complete missions to discover how to use the spore drive to make it back to the prime universe. But beware, or the I.S.S. Charon will chase and infiltrate the Discovery to capture and study the spore drive. Send your crew members to locations on either ships (if you manage to sneak onto your opponent's) to advance missions, sabotage the other ship, and repair your own. Which universe will prevail?

Play as the crew aboard the U.S.S. Discovery or the mirror universe's I.S.S. Charon. Players can play one on one, or they can form teams of 1 or 2 with each person playing a different crew member. Will you be the Discovery's Saru, Michael Burnham, Paul Stamets, Keyla Detmer, or Cadet Tilly, or the Charon's Philippa Georgiou, Gabriel Lorca, Captain Killy, Ellen Landry, or the mirror Paul Stamets? Each crew member has their own unique ability to help or hinder the Discovery. Regardless which side you represent, players will activate locations to advance their goals, teleport to the other ship to sabotage it, navigate nodes on the network, and more!

Tensions will run high as each team hurries to thwart the others' plans! Traverse the tile-grid map and stop the Discovery at key mission locations. The Discovery can travel on the spore network, which they can also manipulate by rotating tiles, while the powerful Charon has to move one tile at a time creating a tense game of cat-and-mouse. Crew members can teleport into the other ship for offensive measures! Some locations activate challenges where crew will clash. Other locations can damage the enemy's ship or detain their crew, causing them to spend precious time in recovery or risk leaving the location inoperable. If any ship takes too much damage, the other side can quickly claim their victory! Use your time wisely as the Charon advances on the Discovery before they can slip away back to the prime universe. Will the crew of the Discovery return home, or will the crew of the Charon catch them first?
