Hunt is one of my favorite competitive shooters in a long time. The boss designs are creepy, one particularly so, and each provides a unique challenge if you manage to find them. And I say 'if' because while your primary goal is to collect the bounties from the bosses you'll also potentially be stopped or stalled by other players trying to do the same.
The nice thing about the competitive aspect is that none of the guns are truly underpowered. Sure they all do varying amounts of damage but often come with tradeoffs to compensate. So like in the crossbow's case, it's a weapon that will kill in one shot if you hit a player in the upper chest or head but the bolt flies slower obviously and the reload time is significant if you happen to miss.
Though Arsene is also correct that it's a very difficult game to play solo. You can queue solo into a duo or trio game, both of which will reward you with an underdog bonus of more xp, but unless you know the map well and how most of the equipment works you're going to have a tough time early on. However with enough practice it is possible to take down other teams while solo. The thing to learn is to rely heavily on traps and be patient.
