Sorry but the game isn't playable yet because it isn't done, and it might never be done. You are free to use, mod, change everything from this game. If someone managed to finish the game (with would take lots of work) then i would be very happy. -----------Warning----------- I think that you can't place units on the field ATM. You are only able to use one unit(horse or infantry) type while playing, else the units will be moved over the current unit. I've only made 3 waves. ------------------------------------ BTW, what the game is about: Defend your empire from the attacking enemy forces, build and recruit units and buildings to survive and to make stronger defending units to your fortress. There is a tutorial in the game if you are new to the the Empire defence game.
