Triple Kaboom Calling Card Bugged?
Is Triple Kaboom (Earn 3 High Octane Medals - Killed 3 or more enemies with a single explosion from a Lethal or Field Upgrade) bugged? I don't see any report on it being bugged. I've been working on my final calling card before 100% in multiplayer and I've constantly been getting triple kills with various lethals such as the frag, thermo, semtex, and spring mine. I've been hard stuck at 1/5 for the longest time ever.
