Bounty hunters are civilians who take the law into their own hands. By specializing in talents, a bounty hunter gains special abilities to help them track down and arrest wanted criminals. Bounty hunters do have arrest powers, but only for their current bounty target. When a bounty hunter captures a fugitive, they collect an often substantial reward for their work.
In addition to special powers, bounty hunters also gain access to specialized equipment such as the Sting SMG with 9mm rubber bullets. This allows the bounty hunter to subdue a fugitive at range without killing them.
