random Halo triple kill

So I was just cruising along on the the new map Avalanche with a scorpian. I killed a banshee, and some other vehicles. I then shot this mongoose for a double kill. A bit after that I get accompanied by the that announcer saying "BETRAYAL". Watch the video to find out what happened, I thought it...

After consulting the Psychic Friends Network, I carefully placed a trip mine on Sandtrap.
