Played a game on volskaya yesterday as zen. Noticed a few times that torb killed me when nothing was on my screen, but I thought maybe I just didn’t see the turret - then I die out of nowhere to torb when I know I was alone in an enclosed room.
Suspiciously, I noticed that when torb’s turret killed something on the kill feed, there was no turret icon as usual, just an empty black rectangle (you know where the ‘arrow’ between the killer/killed usually appears).
On point 2 after our rein shatters I noticed that i got a discord lock-on icon when there was nothing on screen. I fired it and sure enough, it was torb - his model was invisible. The other players on his team were visible like normal.
We won the game anyways.
Is anyone aware of a cheat that does this? Not sure if I should report him.
There’s no downside if you report the player.
It sounds more like a bug, though. Have you looked at the replay of the match?
To appear invisible to all players or to be able to make general engine modifications that are confirmed by the server would be pretty awesome.
This would require the player to make changes to the instance. Apparently, there have been such incidents before. However, I think it’s unlikely. 
Yeah, I was thinking probably game bug but wanted to know if there was a hack that does that.
I guess I will give him the benefit of the doubt.
Like the other guy mentioned, you should review the footage in your list of replays. I’ve caught aimbotters on my own team by using it.
I have a pretty slow computer, so sometimes models take a while to load. Occasionally I’ll get pretty deep into a game and a particular hero will still be invisible because the model hasn’t loaded in yet. Any chance that’s what happened to you?
The “black rectangle” indicates that assets failed to load. Based on what you posted this is definitely not hacking.
Torb + Stealth = PAGANDAN LOS GENJIS!
