If you don't happen to be completely enmeshed in the Call of Duty multiplayer universe, one could easily find themselves lost in the myriad of perks and options available to players -- particularly as the series has continued to build. That's why this multiplayer reveal trailer, featuring a commentary track from game design director David Vonderhaar, is so useful. It helps complete COD noobs such as myself get a feel for precisely what's going on, and what makes Call of Duty: Black Ops 2 different.
Sometimes Call of Duty feels a bit like being in a pinball machine. It's noisy, and there's all these numbers, but I don't really understand exactly what's happening -- I'm just pulling the triggers. That's nothing against COD, which I always enjoy playing, particularly the multiplayer, but it's good to be informed by someone who knows what they're talking about!
