Knights of the Phantom Castle

"Knights of the Phantom Castle" is a (fully-featured) robust strategy game that incorporates massive monster armies, gigantic monsters and stage devices.

During [Camp] phase, build an army of knights, while forging and searching for items.
During [Combat Deployment] phase, decide your army's deployment, equipment and tactics.
During [Stage Battle] phase, take advantage of every control techniques, the terrain and the stage devices, in order to clear the stage objectives and move on.
During the [Camp] phase, use rewards gained by clearing stages to shape your unique army of knights and fight further stages.
