Well there is an island where you fight, when people kill one players castle the player losses...
Every 100 kills you get a new unit on a small island next to your base. On that island you can put the creature on a flower and it will on the main island...
There is also another island where there is old men, when ur attacked and cant hold it you can put them on the rock tent and 10 mercs appears... This isnt the newest version, the newest version is V0.12 i give you a link to it when its bug free;)
