City Builder combines two classic game mechanics in a fun, bouncy new game where players stack pipes, roads and power lines to form ever-larger cities, moving from One to the next across the planet's continents. Along the way, they run into a large number of challenges, ranging from clever/pesky Mole-men to the elusive Bigfoot, Aliens, Wandering Hot-Air Balloons, Archaeological Discoveries, Huge Boss Levels and much More.
