Each round, you roll dice frenetically to get what you want until the timer stops and allocate them gradually to your spaceship board. You use these dice to move your ship around the board, to rotate (different sides of the ships have different shield levels), to use "phasers" (pew pew on adjacent ships and torpedoes) or to launch torpedoes that will follow around the enemy ship.

In solo, you take a pick among four slightly asymmetric fighters and fight against a giant fortress hosting an army of Outer Space invaders. The solo rules, however, have not been revealed yet.
