In the middle of The Heist mission, there is a Data point to be hacked and extract 3 Datamines. Being successful, you will receive components to craft. Before trying, save the game, as you only have one chance to crack it. This video walkthrough will show you step-by-step on how to get all 3 Datamines.

First advice, don’t rush on pressing the buttons. The breach time clock countdown starts only after the first code is added. So you have time to plan and think.

You have to input 4 codes to unlock the 3 Datamines. The trick to do that is to understand the rules around this puzzle.

Let’s list them for you:
0:51 - Rule 1: Code selection follows the pattern Row, Column, Row, and Column
1:03 - Rule 2: Every selected code determines, the row or column of the next code
1:13 - Rule 3: Line codes that are not selected are pushed forward
1:27 - Rule 4: There are only 4 code spaces. If a sequence of 4 codes is pushed, extraction will fail.
As for a sequence of 3 codes, can only be pushed forward once. So if you see a sequence of 4 codes, you need to start from there.
1:50 - Rule 5: Be lucky, some sequences seem impossible to complete.
