As we all know, there are three types of tasks in the game Anarchy Online; they are tasks of dialogue, tasks of killing monsters and cleanup tasks. Among all these three tasks, cleanup task is the most difficult. So here I would like to share my skills in playing tasks of clearing. Players who had done this task all know that after you entering cleanup tasks, no matter how many doors in front of you, there are no more than two kinds of clearing. One is to kill monsters, and the other is to break five lights or crystal to go into the next door. Initially, I killed all monsters before entering the next door. Later I discovered that it does not cost so much effort, just kill the crowd of less monsters or kill the leader of monsters so that Anarchy credits players can go into the next door. As for the elimination of lamps and crystal, you can ignore the monsters inside. You just went to the lamp quickly and break it then the next. After you breaking all the five lights or crystal, you can enter into the next door.
