Sounds like an annoying mode in COD Black Ops I hated because I can't quick scope so when it came to the final two sniper rifles, no matter how far ahead I was, I'd always fall behind and come in 2nd place or 3rd.
C4 Shenanigans are my specialty, I'll definitely be c4 trolling, and tossing grenades at flags before rushing in.
I suicide C4 a lot on conquest, Its funny when they finally catch on to what I am doing. As I run up to a tank I'm getting lit up because they have scouts watching as the tank caps the flag... or even more funny when the gunner and driver jump out but I still kill them both with my blast. X'D
