If you want to unlock all guns try to level up fast and by doing that play Free-for-All HQ pro or TDM(Team DeathMatch).Playing these modes will not only level up your character but level up the gun they are using like if you play free for all and get over 23 kills you will level up your gun as well as your character here are some helpful gun attachments Lethal Tactical and Perks
Assault Rifles,SMG,LMG,Sniper and the rest : HeartBeat Sensor ACOG Scope Silencer and Thermal
Perks : Assassin Pro Scavenger Pro and Stalker Pro
Lethal : C4 Claymore or Bouncy Betty
Tactical : Smoke Grenade Semtex or Tactical Insertion
Remember to watch your back in Free-For-All
