Rules of First Drawn
The rule of first drawn is commonplace on Hive Worlds across the sector, this is usually accompanied by “Unworn Styles Barred”
The rule of first drawn states that whatever weapon you instigate a fight with determines how far the fight will go, a fist fight will therefore remain just that, however if a gun is drawn then it will likely be to the death. No party in the combat can escalate above whatever weapon was first used.
Unworn Styles Barred means that you cannot instigate a fight with someone who does not have a weapon at least equivalent to your own. So if you draw a gun on someone who only has a knife you are in breach of the rules.
You are So Warned. If you break the rules it is likely everyone else in the bar will attempt to kill you with no rules required.
