I wuld like to bring this subject matter back to discuss.
I thought the PUPS were part of the device that maps out terrain. It seems to only just scan for aliens.
I think it would be a missed opportunity if the devs didn't imagine something along the lines of using the Combat Information Center to help out with just that.
Imagine the devs created a mission where there was a catacomb or a veining network (like hundreds of nodes) of xeno infested underground tunnels on the planet that serve as a community hub where random teams would come and stake their claim at the end of a vein once cleared (and also add entries to it with a time stamp)? Much like how death stranding allows players to plant a stake into the ground of the virtual world and add a "hello world to it". Once thats done the game finishes with a "vein mission completion" and the CIC would show these tunnels mapped out like a fog of war style reveal.
Perhaps to play these missions it requires at least one person to have a PUP to progress through the mission objectives.
In the event that these maps would be played out too soon, maybe these maps could be specific to your geolocation time zone. You would only be able to contribute to those in your timezone (but of course they would label it as some other kind of identifier.) It would really help the fanbase let people know about how their timezone has progressed by sharing images from the CIC map.
Imagine we can do that! That would be freak awesome to see what others have accomplished as well as see how this catacomb map reveal over time where people have played it. and some secret areas display ancient engineers have been there.
So to expand on my idea, the node tree would look something like this:
Imagine it glowing, and starting off as a single orb per match then continuing to link and expand as you explore the cavern which the when you put the stake into the ground the next orb appears on the map..
Then we are allowed to render the caverns as 3D scans on the CIC Table.
