The balance of Mortal Online's open-PvP relies heavily on its flagging system. Each player and NPC (Non-Player Characters, Creatures etc) in the game has a flag (color) that is visible to you when you highlight or target them. The color will tell you some basic facts about that player, for instance if it's "ok" to attack him/her or not, although you will never be forbidden to do so by the system. You too have a flag of course, visible to yourself at all times.
Getting to know the basics of the flagging system is easy when playing the game, but unfortunately rather complex to describe. However, when you first start playing, all you need to know is:
Loot from other players and specific objects in the world share this system as well and will be colored accordingly. That means it's ok to loot or interact with all Red and Grey stuff you see, but if you mess with Blue stuff you will become Grey yourself.
If you decide to join a Player Guild that is at war with another Player Guild, special rules apply. You will still see their flag/color, but they will be treated by the system as Grey and so will you for them!
As the system itself will always allow you to attack, steal, enchant, poison or kill any color/flag you like whenever you want, you might ask what the colors/flags are for except decoration. The main reasons are:
This is probably all you will need to know when first starting to play Mortal Online. However, the flagging system goes much deeper than this as it is the foundation for balanced conflict in the game. This section will be updated with more stats and specifics later on.
For those of you that are interested, we've decided to share most of the design we are using for flagging in our Alpha stage. We have to warn you though that it is very complex and fairly poorly commented (as this is what goes on behind the curtains and must contain each and every special case), but it is available for download here. We'll also try to answer your specific questions on the forums!
