I love this game and heres a tip for the boss:You shoot off the mask and blow the hell out of his head. And alot of people have been having trouble with what to buy and stuff well heres some tips
Guns:first start with pistols and use only smg pistols or a rifile recommend a rifle and then buy m-249
stats: WAIT!!! Until u have 18 stat points at lvl 9.First of all add up unarmed to watever u get with 18 points then when you have up to the first yellow bar then go to rifle stats and max it then smg MAX IT OUT .Now for regular stats max out end max out awr maxout lead. THEN MAX OUT THE REST.
TEAMMATES:Get teammates who have better att with rifles and smgs.
Armor: start out with low armor and work your way up.
