Paper Wars is a turn based game, inspired from a number of games such as Advance Wars, Chess and many more. There are a couple very conscious design decisions that makes this game unique.
There are three units: Tank, Copter, and Soldier. Player has only 3 moves per turn. However, they can do whatever they want during those 3 moves, including move the same unit 3 times, or shoot with the same unit 3 times. There is no base building per say, but there are be captureable locations such as a helicopter pad and cities.
