Seriously, why? If someone brings up the topic of "What weapons would you like to see in MW3?", be it online or in real life, all I see or hear is XM8, XM8, XM8. What is the goddamn fascination with it? Why not put in the HK416 instead, which is like the XM8's better cousin? Why use a failed prototype?
So, can someone please explain why everyone wants the goddamn XM8 in MW3? To quote a wise man: Explain this bullshit!
