This usually happens on Convoy Tunnel or Sandtrap when your in a Tank. Your driving along happy as can be and then a zombie starts running at you, You think well I have a tank it'll be easy, and shoot him. He doesn't die you shoot him two more two times directly and he doesn't die. Only when he is so close he can touch your barrel he dies. You check the connection and there is no lag. Can anyone explain or has experienced this phenomenon.
Even if the connection status is green, it may be lagging. Before, I've had green games that lag, and because they're lagging, green doesn't change to red until half a minute later.
Don't shoot him. Shoot INFRONT of him because like rockets it has a big explosion and kills people in the area you shot.
