Last week, some footage leaked from the upcoming Call of Duty: Modern Warfare 2. Though it has since been taken down-with Activision claiming "copyright infringement"-the short video left a lasting impression. It depicted Russian terrorists gunning down what appeared to be innocent civilians in an airport. What made this scenario so shocking was that it wasn't a cut-scene, instead the player was actually controlling the carnage, forced to shoot civilians to proceed. You, as the player, will be given the opportunity to put noncombatants in the crosshairs and pull the trigger.
Unsurprisingly, the leak has garnered its fair share of controversy, with voices shouting out both for and against the scene in Infinity Ward's game. Some say it's a sign of the maturation of the medium. Others say it's tasteless. Ars decided to get the opinion of someone with a unique perspective: a former US Marine.
