Yea exactly as speedy said, if you know exactly where all the bunkers are in relation to your position in the snake, then you will find it a much easier job when it comes to the game.
Do however try an get as far down the snake as u can, this does depend on the snake itself, as often you wont be able to get past the 50 of it, however if there is a large enough opposing 40 bunker on it, get into that. The angles will be easier, you will have more asses hanging out for u to shoot!
However do remember to play it tight, dont start hangin ur ass out to get a better angle if uve got a back guy on u, u will get shot, as a player in the snake attracts a LOT of attention!
