One of the problems with the towers is its kinda hard to figure out what were meant to do with them....Or even what they're for in my opinion, Wouldnt be surprised at all if they turn into a part of a puzzle at all
I posted this a few hours ago:
New Theory to try and answer why the duplicates are needed.
The relics while in their pillars can be scanned, this gives you some data ( unidentified scanned archive ? ) - lets assume that these are actually unique to ALL sites ( including duplicates ).
So if you scan all the relics in their pillars, then do your round of normal scanning as per the a spreadsheet, you can shoot a relic down and use it as required.
Then fly to one of the duplicate sites - now the idea is hopefully the site will detect you have the 4 scans from first site and will reset it's self to a new configuration so you can scan to get new data.
Yesterday, re-got the mission ( after giving up and doing a cg for a bit ) I've cleared all my a,b,g,d,e data, cleared all my msgs from ram tah, and flew to the alpha site ( elmo face ) - I've scanned all four relics and collected all the normal 11 data scans from the obelisks - so tonight I'll fly to the duplicate of this site and see what happens.
Would be nice if anyone can say for certain they have done this recently and got no results. ( I'm sure if someone did this and it worked we would have heard about it by now
