here is another little tip for those of you unable to unlock any good defensive options at lower levels:
'the sniper loadout' - this is the only loadout that will allow you someform of protection. in this case its the kevlar vest (armour/bullet proof vest). all you have to do is pull out your pistol and pick up any automatic weapon (ie any sub-machine gun/assault rifle) that happens to be lying around.
as a noob i took full advantage of this- normally not for my first death as there arent any guns lying on ground at the start lol.
great thread for the new players and those slightly more experienced ones who are still open to learning
