How many people can three C4 explosives kill? I managed to sneak by B objective on metro conquest, lace C objective with C4 (American side), and waited for everyone to backtrack. There were five guys in the blast radius, but I only got three kills.
I unleashed on the remaining two with the USAS, made quick work of them. Definitely one of my finer moments.
might be guys who had flack perk on (those who survived). but you can get multi kills (5+) with one c4 brick if they are packed close together
