Rebuild

Rebuild is set in a scenario in which you are the "leader" of a small city besieged by a zombie infection, and are tasked with surviving the outbreak.

Gameplay
There are five possible difficulties to play through; Easy, Normal, Hard, Harder, and Nightmare. You are tasked to ensure the survival of your population, and have to take various aspects, such as the number of people in your care, their professions, and the stockpiled food at your disposal, all while fending off the increasing amount of zombie attacks at your safe zone boundaries, by assigning some of your population to guard duty.

To ensure that your city has enough food and people needed for survival, you have the option to pillage for food/survivors in areas outside of the city, with the option to scout areas that you have not yet visited, and the option to kill zombies in an area (however, the more severe of zombie population, the more visits it takes to clear the area).

As the game progresses, zombie hoards are introduced, in which a large amount of zombies close in on the city, and finally attack (leaving areas the hoard has passed through with a higher zombie population afterwards), and it is advisable to put enough idle members of your population (preferably soldiers) onto guard patrol so that the danger percentage is less than (or as close as possible to) 10%.

There are also four different methods of winning the game; Closing the portal at the Evil Graveyard (need 15 soldiers, reclaim Evil Graveyard, 10 days, very frequent zombie hoard attacks during), Researching a cure to zombies (need 5 scientists, 3 labs, upto 10 days), Draft a constitution (need 5 leaders, reclaim City Hall, ? days, very frequent zombie hoard attacks during), and clearing the board (reclaiming every square).
