The other day when my bf (level 30 Warlock) and myself (level 29 Titan) were at the Cosmodrome doing patrols and waiting for a public event to begin, we had an unusual encounter with another Guardian. I was waiting in the divide and my bf had gone off to complete a patrol scan….. The public event was about to begin in a few minutes and I asked him to come back to the divide. He told me that he couldn’t get back as a level 2 invisible guardian kept chasing and killing him. At first I thought…… what has he taken? Lol ;) Then I thought if he doesn’t want to do this public event then just admit it, not make up stories! The public event had now just arrived and I could hear my bf getting more and more angry at what ever kept killing him. I decided to leave the public event and go to him to see this for myself…… As I approached him I saw what was attacking him, and now me! It looked like a cloaked level 2 guardian. Somehow he could melee hit us both and kill us with only 2 hits. We on the other hand could do absolutely no damage back to him. We emptied our clips into him at the same time, melee hit him, and still we were taking damage while he was not!! This cheeky bugger kept chasing us and blocking our paths :p Anyone else ever come across anything like this? He remained cloaked the entire time so we think he must have been hacking the game. Would love to hear if anyone else has had this happen to them :) edit 1: From some of your answers it seems like a bug or glitch rather than a hacker. Thanks for your replies, it's still a weird experience however I am glad that other's have had this happen too :) edit 2: haha loving some of your comments guys :D
