carrying a clan mate who's a 29 Hunter through a nightfall I get a random to help but he's whos only a lvl 30 Hunter and a squeaker but Im a 32 TITAN so I can do it no problem. We kill the Walker and I stay back and play Defense so they can make it across. They end up going to Sepics door and waiting instead of helping me so I keep trying to leroy across but die about five times so I start killing everything, that's when I hear the squeaker telling me to go invisible and just sneak through them about 4 times. I guess I hadn't unlocked that perk in my codex.
