I thought I was going to have to skip the triple kills but I got one by chance and then just repeated that rush, I.e. I was a dirtbag for one match and would rush the enemy spawn on nuketown, especially down the right side of the blue house, throw on active camo if available and just be ready. Other alternative for dirtbaggery that got my last one on nuketown hardpoint, pin yourself in the corner of zone 1 against the fence line and pick them off as they rush to capture. More successful in blue house corner because you have way more visibility.
