Hero Online has many special features, such as quests written by various martial art novelists (and many created by Netgame themselves), and a storyline written by Kum Kan, featuring fantastic fighting skills like walking on water or flying over walls. Many other skills can still be discovered further along in the game. There is also a reward system that keeps track of how many monsters a player kills from log in to log out, resulting in rewards consisting of items, exp, and rank. Currently, there are 10 Dragon servers that players can play on. Characters are interchangeable between servers.
   Players can also participate in battles with other players, establishing karma and honor with the more you participate. Karma and honor have to do with the manner in which you kill your opponent, and they appear as titles next to your name. For example... civilian, thug, and novice are all titles associated with karma. Nameless, unknown, and skillful are titles associated with Honor. Karma is received or lost in battles from bounty hunting while honor is affected by faction battles. There are also PvP zones where anyone can attack anyone else freely. There are consequences, of course, to being defeated, such as experience loss. Also a new update can allow players to challenge others of the same faction in a 1 on 1 duel.
