Not sure if this has been cleared up already, but:
In the open world area, it looks like there are 2 different sets of area collectibles, based on which part of the map you select from the tac-map. For example, there are 2 skulls in the first section of the map, and 4 in the back part where later missions are. Are these reserved to the open-world area, or are these mixed in with the levels that I can’t go back and play on my current save?
I ask because I’ve found a couple Forerunner archives in the open-world area that counted towards these 2 sets of area collectibles I see, but having trouble finding other stuff like skulls. I’ve also seen that some levels have their own set of collectibles like Warship Gbraakon and Foundation, but Conservatory doesn’t - so does it have 0 collectibles or are its collectibles mixed in with the “area collectibles” I currently see in open world?
May be a dumb question, but this is frustrating me. Also, no spoilers on collectible locations please - just want to know how this works.
