Just completed the story with Purna.
I'm at lv 70 thanks to Aden's iso mods. :)
Also got a few decent weapons like chainsaw and a few others but can't remember.
But the best thing is I have like 7 M60 guns in the inventory, so if you wanted you could share them out with some friends. This gun is beast trust me.

When you load this save it will ask you to restart but don't worry as the inventory and stuff carries over into a new game.
