With each death in the game, one life will be taken from the Flock’s population. When the Flock’s population reaches zero, the game will never be purchasable again. Only players who have The Flock in their Steam library will then go to the next phase of the game and be able to partake in the yet to be announced climactic finale. After the ending, the game will go offline permanently and no longer be playable.
