Remnant Decryption Puzzle Guide

Remnant decryption puzzles are encountered during Pathfinder Ryder's travels in the Heleus Cluster. Puzzles are found on locked consoles, doors, and containers.

Overview
Most Remnant technology is inert or in a "standby" mode, but some is secured with a decryption grid. Unlocking it requires scanning the correct Remnant glyphs and arranging them in a specific order. The glyphs cannot repeat on any horizontal or vertical straight line or within the boundaries of the interior blue lines of the puzzle grid.

Peebee speculates this could be a safety measure. Even if a method was devised to brute-force hack an interface, it would not work with the decryption grid. Given the devastating consequences when Remnant technology is improperly activated, her analysis seems sound.

The arrangement of the glyphs appears to complete either a password or a code phrase within the grid as a whole. From the little Peebee understands of the Remnant language, they appear to form an almost palindromic "Sator Square" sentence, but the finer meaning would require detailed explanation from the grid's designer.

Mechanics
When Ryder attempts to interface with puzzle locked Remnant technology, an interface will open showing the decryption puzzle.
 * Puzzles consist of a 4X4 or 5X5 grid of Remnant Glyph symbols. Red symbols are locked in place and blue symbols Ryder can change.
 * Sometimes puzzles are missing symbols and this will be indicated by ? symbols. Ryder will be required to scan the surrounding area using the scanner for the missing Glyphs. No Research Data (RD) is given for scanning a Glyph.
 * Each decryption puzzle has a unique fixed solution that does not change.
 * Submitting an incorrect solution to the puzzle will immediately summon Remnant forces around Ryder which will have to be defeated before Ryder can attempt to solve the puzzle again. Each incorrect solution will summon forces.
 * Remnant Decryption Keys can be used to bypass solving the puzzle and automatically enter a correct solution. However, these are expensive items that can be sold for a large amount of and should potentially be saved. While the in-game description of a Remnant Decryption Key says that all consoles can be bypassed, two puzzles can't be bypassed.

Rewards
Depending upon the specific puzzle being decrypted, different rewards are encountered but center on the following three concepts:
 * Game Progression - Some puzzles are required to continue the main story progression and have to be completed.
 * Valuable Loot - A number of the puzzles are for locked containers that contain rare valuable items.
 * Skill Points - A few puzzles reward free bonus skill points.

Completing 20 puzzle solutions in a single playthrough will award the Cryptographer Achievement.

Puzzle Solutions
Each mission page with a puzzle has text describing if Glyphs need to be scanned, if the puzzle can't be bypassed, and a link to the "Puzzle Solution" section at the bottom of the page with a picture of the completed puzzle (or puzzles). The list of puzzles below is a quick reference of all puzzles and solutions that are encountered. Refer to each mission for the specifics of the location and any puzzle requirements.
