How to unlock the Execute Order 77 achievement in The First Descendant - Definitive Guide
You can begin dismantling modules as soon as you start the game by speaking to Silion in Albion, at the far right side out of the spawn point. You'll want to do this to get a large number of Kuiper Shards anyway, but a bonus achievement is always nice. Dismantle a total of 77 modules to unlock the achievement. These drop from any activity you run, and you'll have hundreds by the time you complete the campaign.
Note: As mentioned in the Road Map, many of the cumulative achievements in this game are finnicky, so I would suggest doing this all in succession, or at the very least in a single play session to ensure it unlocks properly. The tracking may reset if you log out of the game.
