This game is still in active development and available to the public for purchase in it's unfinished state, either in Early-Alpha or Beta (or any status in between).
We come out of Space and back in time to the Middle Ages of mankind. The game gives you the technologies of the 5th to 15th centuries and allows you to go wild, building castles, cathedrals and machines of war.
The game is a sandbox for you to enjoy. It can be used as an action game with all-out war, but the intention is for players to unite and re-create the wonders of the Middle Ages.
