The strategy for this map is quite simple. At first you want 2-4 farms, usually you can get 3. Then you want to go to the nearest player's farm, build a training camp. Start destroying their economy, then save up to 2 houses, get max gunnars, then put a rally point on the core of the enemy and make sure you keep producing gunnars. After this you want to start destroying the other player's eco and sending attacks to all of them.
Usually you want to get 2-3 farms on this map then build a training camp to defend your eco and then upgrade to pumps. Once you have decent eco then you want to start making training camps and attacking the nearby players until you have 1-2 players left. Then start getting rigs and destroying their eco.
This map is very unique and has a lot of possibilities. Thanks to alliances coming back this will be a better map for the strategy. To start, you want 2-3 farms depending on the island but if you are on the big island you want to ally one of the other ones on the big island or the one in the small island. When on any island you want to get the gold mine island, once you have that you want to start getting rigs and or attacking if you are on the big island. For the medium island you want to ally the person next to you, then you guys want to equally share then try to attack the little island guy then build eco and attack the others. For the small island you want to get the 2 farms then gold mine island then some rigs and defend the island as it is easy to defend. Then you want to start attacking the medium island then the big island.
