Edit (21 June): Alliance Wars are back, starting from Friday, 22nd of June! Preparation phase starts at 18 UTC on Friday.
Due to the preparation for the upcoming update 1.13 and Alliance Wars improvements, we have now disabled new wars until the new update has been rolled out for players.
We are hoping to release the 1.13 update next week. We'll let you know once we are able to continue with the wars. Our apologies for any inconvenience caused by this!
