Second run through this game. Some spoilers below
It is sort of a new game plus mode. I continued with the characters I had made in my first playthrough. Meaning I was level 48 or so when I started. Enemies where leveled up as well. Still not enough to make the regular enemies any challenge. Actually only a few enemies where a challenge. First round you play as 2B. Soldier type android, second run you play as 9S. Weaker and smaller, as his role is a scanner. Still more than powerful enough. I kept all the chip upgrades I had acquired as 2B. Hacking is his special ability.
I don't really get the story in this game. Adam and Eve seems like they want to learn human history. The simpler robots seems to be copying different parts of human culture. All fights with the two of them this round were way to easy.
