Dealing with glitchers/hackers- if there is a glitcher/hacker that has hacked the game so they are invicible just leave the game or if they have weapon mixed the swam leave . If they are trying to jump out of the stage on what say bunker keep an eye on this area if they try it again kill them repetedly it is likly that they will give up on this or leave the match if they are already out the map if they are on top of a roof like on streets try stick a radiation granade to they this is your best bet at klling they before they get to an area you cannot see them.
