Ceres: Mars Contracts

Mars, amongst the numerous institutions of its thriving colony, facilitates the headquarters of the Asteroid Mining Assembly of Corporations.
The A.M.A.C. council has always had a deep bureaucratic structure consisting of a number of different unions and federations serving mostly their own plans and agendas. It expects your unwavering commitment to integrating their requirements by fulfilling their contracts.

In Mars Contracts, you get to follow certain ways of development in your corporations trying to fulfill contracts (objectives) of different unions. Dealing with these unions will offer you new actions combinations and rewards.

In this expansion the union tiles are introduced. Players may use their leader tokens to take contract cards from the union tiles that provide them with some small objectives that can be fulfilled by following certain paths of development or use specific actions through the game. For every contract they fulfill, each union provides more victory points to all players who contributed by completing their contracts.
