I keep getting them by accident. I've gotten 3 since I started playing rift right before IB. I've also been getting 10 and 15 kill streaks more often. Once I [b]almost[/b] went unbroken with NLB Sidearm in rift. Would've been cool as my first unbroken. But I had no idea and died twice right after the 15 kill streak near the end of the game. Salty.
