Well, I found this "amazing"... I was playing FarCry 2, and snuck into a scrapyard on one of those Buddy Rescue missions. This was the third time i attempted this mission, and for once i had actually managed to get in without raising an alarm. Seeing a gaurd, I decided i wouldnt be able to sneak past him, and pulled out my Dart Rifle to dispatch him silently. I took aim and fired, and started sneaking forward... when I heard an explosion. apparently, the Dart had penetrated an oil tanker(which i thought at the time was a Railcar) and blew it up. Shot to ribbons, mission failed, had to restart.
