Players WIN as soon as all 24 spaces on the Containment board are filled with cubes, with one of each color and value. The Tesseract is deactivated and the world is saved!
Players LOSE if the Breach token moves onto the last space on the Breach tracker. The 7th Breach rips a hole in space/ time that destroys us all.
Players also LOSE if, at the beginning of the Threat phase, there are no cubes left on the Tesseract. It detonates and we are removed from existence.
