Player versus Environment.
This game mode is in which the players face against the environment of the game. It includes a series of enemy villages that will be unlocked as the campaign progresses. To improve replayability, villages can be attacked multiple times. Players who play this mode are not in danger of being attacked by other players and/or having their resources stolen.
There will be no limit to daily attacks, but each time the players want to attack the same village, they will give fewer resources, until a point is reached where the cost of the attack is equal to or greater than the resources that can be obtained from it. To be able to get resources again consistently, players will have to wait for the daily server restart.
As the player progresses through PvE mode, the difficulty will increase, but the rewards obtained will be greater.
