Let's talk new modes. You've got your standard
Call of Duty spread; the stuff that you'll never see missing. But there are some interesting new ideas that work really well. Cranked is a clever idea that, based on its name, is probably inspired by a certain Jason Statham flick. When you get a kill, a timer starts. If the timer reaches zero, you explode. The only way to stop yourself from exploding is to kill some more. Granted, the most immediate danger in Cranked is simply getting shot, but it adds a fun dynamic to the frantic action.
Blitz is another new one, and it's a mix between football and capture-the-flag. Each team has a base, a tiny colored cylinder of light. Your job is to keep enemies from entering your base while trying to run into your enemy's base. Each time someone runs into a base, a point is scored, and cooldown period of ten seconds begins for the base that was scored on.
Search and Rescue is a twist on Kill Confirmed. Once a kill is confirmed, the one you killed cannot respawn. However, if the kill is denied, the one you killed is resurrected. It's a neat idea.
Gameplay is classic Call of Duty, with a handful of tweaks to the gameplay. Developer Infinity Ward wised up and realized that a single swipe of a knife likely wasn't enough to even incapacitate the hardest of soldiers, so now each knife kill is more intimate, time-consuming, and, well, Battlefield-esque.
