[@13900IpForThis] Something like a heavy crossbow can be used for a variety of purposes - for example, it's easier to rig up a crossbow bolt to explode than it is a bullet - but generally speaking they've been replaced by guns for the most part. However, notably there are no suppressors for firearms, so if you wanted a rogueish assassin type, crossbows would probably be best.

Monster hunters also use crossbows, but they're not usually employed by the World court.
