I don’t understand what you are saying about save files … are you talking about in-game save games?
If that’s right, then, as a guest in a game, fully recovering Jack’s abilities is impossible if the host doesn’t have them, right ?
Yeah and for me it was my first saved game (slot 1)
But for my coop player his first saved game was (slot 3) and we started a new game on slot 1 and it didnt transfer the Jack progression which is why i think it dependant on your saved games.
@Fabjo06. Yes the ingame saved games. If your playing on xbox you press Campaign, New Game +, there will see Save 1, 2, 3, 4, 5 ?
For me my fully upgraded Jack is on my Save 1 play through. So when i started a new game using Save 2 it took my progression from Save 1 / previous game / Original Campaign. Im at Act 2 with Save 2, when i started another new game i used Save 3 i am going to believe it took the progression from Save 1 but they both (Save 1 and 2) have fully upgraded Jacks.
Just to add I did try with my coop player as host doing a new game on Save 4 when the Jack was upgraded (apart from 1 upgrade) We started a game on Save 1 No Jack progression. We tried Save 4 With the thought it might take the progression from the previous game Save 3 (with the jack progression) but this didnt work. Also deleted Save 1 tried it again on Save 4 as Save 3 would be only save left (with jack progression) didnt work.
I think it literally has to be Save 1 for jack fully upgraded for it to work, i reckon thats what they mean by where you left off in the original campaign. Original being your first game maybe 
Is your friend by any chance a PC player? Or are you?
Both Xbox
After several tries, if you are as a guest and the host has no progress for the Jack’s abilities, this does not recover them (those acquired during a previous complete campaign) and also adds a bug that makes the flash and the scanner unusable as if they had not been acquired.
On the other hand, as a host, it did recover all the abilities (with a few moments when the active abilities no longer worked: a restart of the game was enough to find them)
Now I’m pissed off with the matriarch who is invulnerable: bullets have no effect on her weak spot until she thaws.
Cryo Cannon or shooting/blowing out the ice underneath her will also expose the weakspot once frozen.
Cryo is just more risky as you have to judge whether you can freeze the Matriarch before it charges you down due to limited range.
So you did manage a get a game with “your” jack progression instead? If so thats great. It does make higher difficulties more fun rather than live and get one shotted 
yes as a host but I would have preferred as a guest
I know it, the problem is that there is no damage when I shoot her on her weak spot when she is frozen … as if there is still her protective skin because it looks like the bullets are ricocheting. The damage is done as soon as it is thawed.
I will try to make a video for a new topic because I am approaching 10 trials and it tires me.
In the end, I succeeded to kill her by combining flash and grenades

Or you BOTH play on Incon and hate life for a solid 20 hours.
That’s why this thread came up in the first place.
Yeah i would have preferred to of not been the host too but it ls a whole different campaign experience with Jack fully upgraded from the beginning and we wanted to try it.
Jack as a NPC is probably much better since it’ll almost never go down. By playing it yourself, you go down (or die rather) pretty quickly once you use a skill and the enemies start shooting you. With Jack as a NPC you can just keep stimming and you should be good to go. You can also use the invisibility instead with similar results.
I have been using a mix of cloak and barrier, for me Cloak is best to deal with the juvies and rejects as one hit and your dead.
In Act 1 a reject was climbing over something, i was on the opposite side to where he was going behind him and i died, like what the hell man! 

i could not deal with Ironman
I can only take it so many times on Escape with the constant reloading and the cutscene all over again.
It would be good if Ironman in Escape just took you back to when your in the pods and burst out rather than all the cutscenes again, i think people would attempt master runs more if that was the case, Too time consuming😂
I did always think 3 player would be the ideal way in doing higher difficulties but it makes sense to leave him as a NPC. Im playing Solo on Inconceivable and Del is always going down and taking out enemies for me. I give him like a boomshot or dropshot when i find one, in a different playthrough i gave him a mace he had it for ages it was hilarious
I know some could find this workaround for this situation, but its worth writing about it here.
Me and my mates did encounter this bug, guy playing Del literally quits game to let game save checkpoint properly. Then he joins back and reload checkpoint
I managed to get around it too.
During the load screen i was just ready to move straight away and then cloaked until we got JD, second or third restart. Its defiantly an issue they need to address.
I reported thid bug day 1 of the game as I did it on insane blind. Not fix’d? Typical TC tbh.
It’s really not that bad IF you get every Jack-upgrade and spam them all the time.
