In Gravwell, players command spaceships that have been pulled through a black hole, transporting them into a different dimension. With each ship lacking fuel to get home, each player must collect basic elements from surrounding asteroids, using the gravity of the dimension and what little resources they have in order to reach the warp gate that will take them home.

But in this dimension, moving ships will travel towards the nearest object, which is usually another ship, and when those objects are moving either forward or backward, reaching the warp gate isn't always easy. Time is running out to save your crew and your ship! As a grim reminder of the cost of failing to escape, the frozen hulks of dead spacecraft litter the escape route — but with careful card play, you can slingshot past these derelict craft and be the first to escape from the Gravwell!
