Data Cubes
What is a Dekyu?
The Dekyu are collectible blue cubes scattered through the Digital world. Collecting them can reward the player with achievements and there is a NPC that gives rewards based on certain collection goals.
When searching for them, current area progress will be shown in the Map (M key) as follows:
Notice that all Dekyu are Numbered and a Check mark shows up when they are collected. The list of locations below will use that same numbering system to help indicate which ones are missing.
Some Dekyu can be locked behind side quests or unlockable/ hard to reach areas. It is recommended that players take their time while collecting these.
Dekyu NPC
For the list of Dekyu locations below most of the credit goes to the Korean community and Josma.
To read the map easily note that the cubes show the exact locations and the numbers are to help track missing Dekyu since drop down menu at the top right of the map(M key) shows the list of collected ones.
PS: Some Dekyu may require side quests or jumping on hard to reach terrain. On those cases a location tip will be listed under the map.
