2009's Call of Duty: Modern Warfare II is remembered for, among other things, its controversial "No Russian" mission in which players walk alongside a terrorist and can murder innocent civilians in an airport. Designer Mohammad Alavi spoke to IGN about this mission, saying some people inside developer Infinity Ward objected to it and said it was offensive. Additionally, Alavi discussed how a military veteran was brought in to test the mission and he ended up putting the controller down and walking out.

"There were definitely some people at our company that [objected to No Russian]," Alavi said. "I thought they were overreacting, but they were 100% right. I remember one person was like, 'This is offensive. I don't want to play this level.'"

Infinity Ward co-founder Jason West made the decision to include a content warning before the mission and give players the ability to skip it entirely. Alavi didn't originally want to do this because it felt like "copping out."
