I'm older than I want to admit here, but I just bought an Xbox One and COD:Modern Warfare and Cold War. I've played through both campaigns (in Recruit) and have now started playing online. I SUCK! I got this so that can play against my son, since he's living quite a distance away, but I want to be at least a REASONABLE challenge for him to kill. When I go online, I spend more time watching through the Kill Cam than I do running or shooting. I have managed to level up to about 15 or so, but man, this is TOUGH! I'm sure a big part of it is my age and reflexes, but I sure could use some help here! Any tips, tricks or suggestions?
