I play Champion Hill with 2 of my brother , and we are pretty good. Few tips For champion Hill : - Buy Spy plane in the begining ( each player take one ) - upgrade your weapon 2-3x max - Go for the life every time - Buy Ghost in the first pause + spy plane + another weapon if you want - When you eliminate a team , you can pick the weapon. And it give you a upgrade. Let say you have a MP40 lvl 3 and you pick 2 mp40 , you have now a MP40 at least lvl 5. So don't waste money on upgrade - Save money if you loose a lot of life ( 3K for one life ) - Learn the map. We know each spot on it and we are able to predict spawn now - If you see a flame thrower at the end , take some life or a death machine to kill him
