The underrated Spectre with rapid fire was... I mean, I'm not kiddin' you, the best ever. With the combination of marathon pro and smaller maps, grenades AND claymores, 8 kills for a Blackbird, UAV spam, the game was, as a rusher then, a rusher's dream. ...And a broken dream for some. But, Black Ops 2 killed that dream for me and I shifted to Assaults.
