I wish I had taken a screenshot of my best xenocide so far. Here's the story, in any case.

I was lucky enough to hear that flashy "building created" sound in the next room, so I ran out to see what they were up to. What do I see but four marines huddled around a turret factory outside one of our hives. I scurried up the wall, ran across the ceiling, triggered xenocide, then dropped
on top of the factory, and exploded. Getting five kill/death messages at one time is a sweet thing to witness, and it's even better to be the cause of them.

I loved it!! As soon as my claws hit the top of the factory, all four of 'em backed away a step and hauled out the guns. Just as they were about to start firing on me,
BOOOM!!!
I really wish I had a screenshot.....
