61-1 on Cracked GW Dom. KS: Sentry Gun, BB and Dogs. I was running Scavenger Pro / Hardline Pro, SoH Pro and Hacker Pro / Marathon.
Setting up the SG at Dom B facing the enemy spawn = orgy-porgy of kills. And since GS/CG aren't that good on this building environ, Dogs and a BB for campers did me oh-so-well. Oh, and picking up a multitude of enemy weapons for a weapon-KS (without Killstreaks), up me at like 27+.
My best MVP performance was on Jungle the other day. 57-1, CG and Gunship rape. Only death was trying to get this guy off the sniper rock. Took out his Claymore, fragged him and nothing happened so I popped off both concussion bombs and dude panic sprays me. Would have been the final killcam had I got him. Flak Jacket and its users can burn in hell.
