From Bls Hepcat:
Heres the scoop, its an invisibility glitch that only the host can do.
The host has to meet a certian criteria though. He or she have to be a Spec-ops and have to equip a MP7-SD with light body armor and its only on the map clinic.
What happens is the host is able to go into some sort of ghost/invisible mode after almost being killed with 1% health remaining. You have basically no life left on your bar but your not dead. This somehow makes you invisible until a random grenade or something kills you. But you can still shoot and kill people.
I would like anyone to try and recreate this glitch too so we can send it to UBI and we can get a patch.
This reminds me, last night I was in a small game on hideout, and at the very start of the map I could only look in one direction, if I turned around everything would be black... I told me team mate about this and he said I was invisible, he could only see the green marker.
I could actually see the inside of our base from the outside, I ran into the base, came out the other door and everything was normal again, and my team mate could see me.
no idea how that happened, don't think it's common
Ran into something like this last night, the host "Claimed" that he got stuck in a wall, he was invisible and kept capturing an "alpha" sat over and over, we had the sat covered and he kept doing it..(the sat was inside a building, lower level and in the corner of the room, forgive me I'm new and don't remember the name of the map, but it is the one with the large courtyard in the daytime with a bridge over it.)later on (I didn't see it..) someone on my team claimed they saw someone leaning THRU a wall to shoot...also this paticular team had a Ballistic shield yet the hightest level was 14 (sorry not really sure what level you need to be to have that..so just excuse me if I'm wrong)...anyway this is just what I have heard and seen that seemed "off"
SInce I'm a Host most of the time I'll spill the beans on this one. It's not an intentional glitch nor do you really realize it when it happens although you are apparently close to or dead by the health meter. I'd say it happens to me since I now notice it, 6 or 7 times in a hour session. It happens on most maps regardless of weapons or armor. It seems to occur when you kill someone at the same time they kill you, but you ( the host) stay's alive. You don't realize your invisible untill the other team starts just walking past you. I've followed people around walking in circles in front of them, tapping them a few rounds in the leg and watching them spin around etc. I've also heard of other hosts (MANY OF THEM) that will just go to a spawn area and Camp for around 50 kills. I've known about this since day one, but I just found this forum after even calling the UBISOFT offices here in SF. Just wanted to let you know it's a real glitch and it's not a LAG issue at all.
