Official Press Release:

Voyage Century Say No to Vicious PKs

In the current edition of Voyage Century Players who attempt vicious PKs will be defined as a Player with a Red Name and will be attacked and thrown into prison by guards when their notoriety degree reaches a certain amount. Thus they must reflect on what they have done in the prison cell before the system will release them, clearing their notoriety and returning him to the state of a normal player without the scarlet letters. Anyway, we feel this treatment is not strong enough for serial PKers, thus we are striving to improve it in the upcoming new edition of VoyageCentury.

The new edition has been updated with the Hunting Roll. When use the Hunting Roll you are switching to the state of hunting after buying it. If you shoot down a Player with a Red Name whose notoriety degree is 10+, he will be thrown into prison at once. The effect of the Hunting Roll will last for on hour.
