Funny sorry for you. Remember that centurion Oryx "took" ... Wait, wrong story. (My story has a better ending anyway) My friend (tedain84) and I had just completed a Public Event on Nessus when I found and killed a High-Value Target. When my friend came to get the chest, I punched him in the face (because why not?). Then he asked me what I did and I told him that I punched him. He moved and asked me to punch him again (?), so of course I obliged... twice... and he DIED! Is there a friendly fire option that I wasn't aware of? (I know the answer to that question is "no") Just wanted to make you aware of this bug. If someone found a way to exploit it and start killing other guardians outside of the crucible, that would suck. For additional information: When I first dropped in to the public event via fast travel from another part of Nessus, I saw other guardians shooting at ... nothing (there should have been a giant servitor there). My friend couldn't see it for a minute either, but then he could and joined in the fun. I had to fast travel to the same location again for the servitor to appear. Once the event was over (and I had killed my friend) he told me what he saw: He could see my guardian was standing down by where the event had taken place, holding my ghost out and not moving. Meanwhile, there was a blur moving where I was actually standing. He had me come stand next to the immobile version of me (that I couldn't see) and took a screenshot. https://imgur.com/a/LZo4r The awesome Titan with mismatched, un-shader-ed armor is what he saw frozen in place. The blur above his spiffy raid scout rifle is where I was actually standing. It was the blur that killed him. Here is a link to the full video of the friendly fire fail: http://xboxdvr.com/gamer/PadisharBrazil/video/37700383 (I kept shooting at the box because he couldn't see where I was standing. And yes, I missed twice before I actually landed a punch. Thanks for pointing that out.) Here is the video again with some clever audio editing (done by another friend) that makes the clip much more entertaining: https://www.youtube.com/watch?v=bzFled7UNP4&feature=youtu.be (Please watch this! It's funny!)
