Overlord is a real-time strategic warfare game where the player must manage large standing armies, economic capital, and political stability throughout a number of extra-dimensional star systems.
As the dictatorial ruler of the Epsilon Galaxy, the player has obtained complete, indisputable authority. However, during a scientific experiment in hyperdrive technology, Epsilon scientists discovered four "buffer" dimensions, each containing a number of barren planets that exist between the Epsilon Galaxy and another alien dimension. Unfortunately, the most powerful empires from these alternate dimensions have also just discovered these zones through their own experiments. The player must battle these alien species for control of these buffer worlds, to ensure that their rule in the Epsilon Galaxy remains intact.
Blood will have to be shed for supremacy of the hyperspace planets, and for the player to become Overlord of these four new dimensions plus their own.
