Mars

Mars is one of the early Zen Pinball original tables, first released in Zen Pinball for the PlayStation 3, and is also part of the 3-table Sci-Fi pack. It is inspired by future visions of human expeditions to and exploration of the planet Mars, and involves completing missions to navigate its rough terrain and unveiling its mysteries with advanced technology and vehicles in the year 2100.

Even though Mars and Earth Defense involve interaction with aliens, the events of Mars do not precede that of Earth Defense because the events of the latter's plotline predate that of Mars. Thus, Earth Defense is not a sequel to Mars.
