Just wanted to share an extra challenge if you guys want a little more. So here it goes. Me and one of my friends playing coop mode, St. Obligartus Church. I sneaked up in houses while he took overwatch by the streets, taking out potential threats. On the church sound, he started picking off targets. Then I have a killcam he made, still under cover. He was actually shooting to the tank in the streets. But the tank never exploded. In fact, he was shooting at its little window on the front or something, because it was moving. So the bullet landed there, then the tank literally stopped. It was not able to move anymore, like if he just killed the driver. The tank was still able to shoot. I tried so many times, never managed to do it. I'm sending you an actual screenshot of the target you need to shoot. My mind was so blown away at this time, I never thought about taking a screenshot. Hope it'll worth it ! (: http://steamcommunity.com/sharedfiles/filedetails/?id=113223771 (I'm trying to get it).
