I can't believe this thread is still alive! I remember reading this several months ago. Anyways, I probably already mentioned it, but I'm thinking that it's like the kill by falling (Iiiiiiiie) where you have to drive an enemy that has full health off a cliff. So to get the bomb explosion kill, I'm thinking that the enemy MUST have full health. Also, there have been cases of bomb explosion kills on Narrows and The Pit, so any ideas involving vehicles are most likely wrong. I think it may have something to do with equipment or another object on the map. Here's an incomplete list of maps where it has occurred on: Sandtrap Valhalla Rat's Nest Last Resort Standoff The Pit Narrows (If you know of more, you can update the list) Kasaiken and Joel: don't give up
