Ghost Pro and Hacker Pro have got to be the best perks on the game.
Spy Planes, Motion Sensors, Turrets, Cobras, Hueys, IRs, Camera Spikes, Valkirie Rockets and everything else cant see you. Not even Blackbirds can. Just make sure you stay away from your teammates that dont hav Ghost.
With Hacker Pro, you can see and enemy claymores, motion sensors, and turrets and hack them to make them yours. You get better care packages, and can booby trap enemy care packages so that when they try to get it, it fuckin explodes in there face. funniest shit ever. but apparently those two perks are the new juggernaut perks...ive been called a Ghost fag too many times to count.
Im really liking these perks right now...Flak Jacket/Ninja Pro with a shotgun...Lighweight Pro/Marathon Pro/Scout Pro fpr run and gun....not having to put stopping power on everything has liberated me.
