Infinity Ward's promising 'best in class' multiplayer with Call Of Duty: Modern Warfare 3.

While its single-player experience is pretty much guaranteed to be a mouth-watering roller-coaster ride, many are keen to see what's changed on the multiplayer side.

Headline features include two new modes called Kill Confirmed and Team Defender. These take existing multiplayer hallmarks and spin them on their head, creating completely new strategies. Team Defender in particular — which appears to be a mix of Capture The Flag and Oddball — definitely has us most excited.
