Great moment in Modern Warfare 2 for me tonight, was playin Ground War and got a match of Team Deathmatch on Underpass, and had an absolutely epic moment where I got rushed by 2 enemies with me using my ACOG'd Slight of Hand Stopping Power Steady aimed Intervention. I quick scoped the first one and got a headshot, and then no scoped the second one. This for me isn't exactly anything special, however, the no scope shot went through the wall behind him and hit someones Claymore/C4 also, which set off another Claymore/C4, which killed someone, giving me the "What The ?" and "Dominos" challenges complete, for killing an enemy using bullet penetration to shoot an explosive device through the wall, and killing an enemy by setting off a chain reaction of explosives respectively.
I shat my pants when it happened. The guy I killed must have been screaming bulls***.
