So what about the Sentry Gun, then?
Does that add kills to my streak as long as it kills some people while I'm still on that same life? Or does it have to kill a certain number of people before it adds a point to my streak counter?
As for getting triple kills with the TR, it's AAAALLLLL luck. You need a tightly packed group, then just send all three rockets blazing into the pack. No amount of Blast Shield and Riot Shield equipment will let them survive such a thing.
