Personally I obtained with my nomad for my first part the supposedly secret end (I do not see what is secret) I wanted to let Johnny and Rogue take revenge, but by remaining V at the end.
( Good sight that rogue was killed, that panam left me to leave with the nomads and that I found myself in space (I did it again) to leave with panam and the nomads )
