// bounty hunt is a mode that was clearly pretty heavily developed, and had alot of scrapped concepts (i.e. most wanted player bounties, turret bounties, collectable blackbox objectives)
// in the interest of time, this script isn't gonna support any of that atm
// alot of the remote functions also take parameters that aren't used, i'm not gonna populate these and just use default values for now instead
// however, if you do want to mess with this stuff, almost all the remote functions for this stuff are still present in cl_gamemode_at, and should work fine with minimal fuckery in my experience
