Update 09/05/2014: New building on Facebook platform & new monster
New building: Dungeons on Facebook (PC) platform
So, what is the Dungeons building for? "Enter the portal to the Dungeons! Can you and your best Monsters battle through each dungeon and claim the ultimate treasures? Try it now!". Of course it will be a place for us to join the Dungeons Battles, which has been available for iOS before.
Although the building has been released, but The Dungeons is not yet available!
In my opinion, this building is similar to the AirShip building. It has level, so there would be a relation between levels & the difficulty of the battles?? No one knows, but one thing we know for sure is this building has not yet any function. The Dungeons battles in Facebook are still under developing. But because of the release of the Dungeons building, we should believe this will be available soon.
New monster: Arnu
