Okay, I've been trying to complete this challenge for a while (it's the only emblem I'm missing for my first emblem page). I just have a few questions.

Does it have to be a multi-kill? (e.g. 4 or more people?) Or can it be double/triple?

What's the best map to do it on?

And... are there any strategies to do it?

Thanks, 808.
