Ok first a quick update - your squad members levels drop to 1 when on your first field mission but Carter's remains at 8. They all level up as usual though. Now like I said, I downloaded from the Mediafire link and I think the save I used was XSaveCPrelude_1 if memory serves me, at my age that's questionable.
God mode? Inf ammo? I don't think so, I guess this game's saves are tricky to do and whoever did these saves has not returned to this post makes this more and more likely... but I like the way you think
Great work as always I'm just about to start playing this thought I'd give it a go, maybe you do something with the new Xcom Enemy Within like you did with Enemy Unknown, its basically the same game just a expanstion really same as unknown just with few extra new abailities and stuff I have a save where its just after finishing the tutorial where I can start to unlock and purchase stuff if you want it to take a look let me know Oh yeah can you remember what difficulty this was done on?
