For generations, the rats in the old junkyard have been telling each other the great legend about a moon made of cheese. And now they have made up their mind: they will build a rocket and take over the Cheese Moon! Though the rats share a common goal of a lunar-cheese landing, different families of rats will be competing to contribute the most in the name of honor, glory, and cheese consumption.

Played solo or with up to five players, players will enjoy numerous strategies, special abilities, and variable setups to create fresh and exciting gameplay each time First Rat hits the table. On every turn, players will decide whether to move a single rat five spaces, or multiple rats up to three spaces, only possible when rats end their turn on spaces of the same color. Moving onto occupied spaces is only possible at the cost of cheese. Players will navigate their rats through the junkyard, collection resources, buying or stealing useful items, and building rocket parts in order to achieve the most victory points.
