Why was it changed/removed? Seems like very cool fun content imo.
because is part of 2nd thargoid war longtime event, now completed (at least this chapter) if we can consider "completed" a war without declaration, truce or armistice;
we still thinking from a human point of view, even the
meaning of win or lose.
btw, i think FDevs will not throw away all this good content, simply from a game developer point of view and business... in last twitch stream of 2024 they said we haven't seen yet the biggest Thargoid vessel, so i think this content will come back, reused, in small or big scale events.
meanwhile, my suggestion is to discover the lore and visit not only Spires but other sites, thargoid and humans (ex.
INRA)
old Goid
Surface Site have a couple of nice mini event to trigger and mats to gather,
Barnacle Site imho have the best (passive) goid event.
would be nice in future to explore a Thargoid site, "turn a corner" to come face to face with a "on foot" Thargoid survivor, remained stranded and split from the hive during the retreat... surprise!
