you could get a better gun so you could get snipers, pistals, shotguns, subs, and maybe a riot sheld
the wepons wold mainly affect the look but minorly how it shot (sniper one shot longer range) (shotgun short but more power slitly) and riot 3 hito kill but deflects 2x as much dameg)
also better and different armore like coosable colares and shoulder pads and helmets
