Barrage is a resource management strategic game in which players compete to build their majestic dams, raise them to increase their storing capacity, and deliver all the potential power through pressure tunnels connected to the energy turbines of their powerhouses.

Over five rounds, the players must fulfill power requirements represented by a common competitive power track and meet specific requests of personal contracts. At the same time, by placing a limited number of engineers, they attempt to enhance their machinery to acquire new and more efficient construction actions and to build and activate special unique-effect buildings to forward their own developing strategy.
