This thread is about what Night City could be and what we might see.
So what do we already know???
Story line
We know little about the storyline but we do know that the Alchemist is likely going to be filling in the role of the clairvoyant to continue the story after we see him appear after the Clairvoyants death. We also know that we have to battle this other boss thing that shattered Eddie's soul. If this is in Night City we don't know but likely we will see him. The Beast might also be reincarnated and might have to battle him again.
Rewards in Night City
Rewards will likely see new talismans (least 4 to 6 new ones), Non-coloured xp shards and maybe the addition of non-coloured runes. We will definitely see Evolution shards and runes and common souls. On the madness level, they might give legendary souls or frontier coins. I think that once you finished the normal level and clear the boss level if there is a boss you earn a 4-star killers Eddie.
What Night City will look like
We saw our sneak peek of Night City from the State-Nation 2018 post. It looks promising.
Characters
New characters like the ones from Maidens first 3 singles along with maybe older characters that will be recycled. This new world likely will only new characters.
Skull Quests
There should be a new addition of skull quests based on one of the levels in Night City. What the rewards from this Skull Quest will be we do not know.
Anything else
That it is definitely coming and that its been in the works for a long time. Should hopefully have no bugs as Rags said.
