Attack Dogs. At the moment I hate them. A reward for a long kill-streak (7?) equivalent to the attack helicopter in COD4, I haven’t yet managed to earn one so I’ve only been on the receiving end! They’re a pain, they get in your way, they distract you and if you don’t kill them or leap out of the way you’re dead. Fighting off the dogs spoils any momentum you had built up and makes you a sitting duck if an enemy is following the dogs in.
Otherwise COD WW is a great laugh, I’m certainly hooked!
