This is a idea for a new type of missions (obtained from buletin board), but not generated by algorithm, it could be feed by player. How it could works: some player pays some amount for the head of another player (someone disgusting, a pirate, etc!!!
), then he feed a form to create this mission. The form could inform several aspects of the target, like the why of this assassin mission, the locate of event, when that target player used to appears, etc...
