Propably i have seen this today, one of my teammates was almost immortal, he crouched at a supply box while an opposite player started to shoot at him and shot him 10 times from 5 feet away, my teammate ignored the enemy and collected the items of the box.
He was always engaged in fights while I was often on the different side of the map (maybe the running cheat). He was not completly immortal he died several times. He had no problems to win a fight against 3 people confronting them on close quarters using only his guns.
Feeled sorry for the opposite team one player was really good, but no chance to win against us with this cheater.
Yes, cause that will definitely get him banned! NOT.
Sony can't do anything against people with jailbroken ps3's these days.
If they ban the console-id, they just get another one or spoof it.
And that's if they even get banned, most of them aren't even showing up on Sony's radar because they modded their ps3 to appear offline.
All you can do is hope for a PS4 version. Untill that get's jailbreaked.
On the checkpoint map earlier I spawned in the upstairs of the building with the ladder on the front, jumped through the window, hit run and jumped off the ledge to go collect supplys from the box below, my teammate who had just spawned in jumped clean over the white van and I watched him sprint the whole map without stopping although he could be killed.
Unfortunately like already posted there is so many cfw ps3's out there along with other cheat methods not a great deal can be done about these invincible cheaters unless we end up with consoles performing like the xbox0ne was planned to, with console locked games etc. It would be nice to have Sony do topology checks on console discs like on the 360 (XDG3) to crush some of these people but again that could also just end up bypassed as with xbox360.
Just try and remember these idiots that need to cheat cannot achieve a decent level of skill and as much as they boast their stats/level they didn't achieve it and when they try and tr011 you ignore it and feel sorry that they are pathetic lamers that have empty lives they need to fill.
Personally I just leave the lobby and play later after they have gone.
I would point out with a healer/gifter on the team sometimes it does look like someone is cheating but a lot of the time there is a player behind them holding x to bandage them and crafting/gifting bombs/molotovs working as a near indestructable team.
The concept of TEAMWORK seems lost on many players on TLOU as the run round like it's COD etc.
