So first of all, I saw this level and it looks like BOSS Fight (3 or more bosses) so I guess this level like a BOSS Fight from CI3, CI4 & CI5. This is gonna be good idea!
Second picture:
That icon looks like Rocks from CI3 & CI4 . Like this:
The last picture:
This level was from Chapter 7 on CI4. This is actually when you went to the green space right?
I think that they will be in the full release. Also in the first 2 versions of early access i saw 1 yellow star that doesnt have ANY missions. I just click on missions and i found nothing(no they are not locked). I forgot how it was called, but it was in the begining when all players was start.
