Having trouble finding all the DataCores but still want a sneak peek to inspire your continued search? In Zetria the archive has five rooms to the right which can be accessed if you have acquired the correct amount of DataCores allowing the player to conduct *research* for scientific purposes. Rather than record the whole clip of each encounter and completely spoil things a before and after pic is shown.

Just a heads up that while there's 9 DataCores to collect you only need 8 to unlock these doors. Not sure if this was intentional or for future content.
