ReCore

Dungeons are spread out across the maps and will not show until discovered. Generally located on the perimeter of the map, with the exception of Shifting Sands where four dungeons are located down the central line. There are 17 in total, In order to earn the achievement you must complete each dungeon once. The secondary objectives are not a requirement.

Unfortunately simply discovering the dungeons is not enough, every dungeon has both a level requirement as well as prism requirement and on top of that in many cases you will be required to locate a number of power cells in order to open the dungeon door. Usually these power cells are located in the vicinity of the dungeon, however in the case of the Pit of Oblivion they are spread out across the map. A video guide for acquiring those particular power cells will be at the bottom of the page.

Pit of Oblivion Power Cell locations. Hope this helps I spent over an hour trying to find all the cells.

There are 17 dungeons currently available as part of the base game. There is Quicksand Rally as an 18th dungeon (which you can play and complete without the T8-NK frame which is not currently in the game), but likely doesn't count towards the achievement.

Dungeons consist of either Arenas (single room, fight till finished), Traversal (like an obstacle course), and Adventure (kind of mix of the other two). All have the same secondary objectives: finish before time expires, collect the yellow key, shoot 8 target cubes.

You will need a minimum of 75 prismatic cores to unlock the final dungeon, Tyrant's Forge. There is also an infinite time glitch posted on the forums, allowing you to complete the dungeons without worrying about the time restraint, allowing you to play at your pace and find the keys and target cubes.

Not sure what constitutes completing a dungeon, whether simply finishing from beginning to end or if the secondary objectives are required (should get anyways for cores and blueprints).

This finally unlocked for me after booting the game up from the October 5th update, and unlocked during a loading screen.
