During a seige trip over seas, you hit a storm that puts you stranded on an uncharted island. Now you must survive on the land untill you are rescued. First off, you must live off the land due to all trade routes being cut off by sea. Also, beware of indigenous peoples to the island as they will attempt to rid their island of invaders. Your only goal is to survive on the island.
UPDATE: I downloaded it to make shure it plays properly, but when I played I noticed that all the arabian Swordsmen were erased from the invasions.
