How to unlock the Hydrogen Bonded achievement in Assassin's Creed Unity - Definitive Guide

100% Requires:
All Main Story Mission w/ their bonus objectives
All Murder Mystery and Franciade side stories
All Outpost missions
Both Co-op missions
All collectibles (Napoleon bicorns, chests, artifacts)
All Viewpoints
And all of Suger's Legacy riddles

You can check on your progress with the progress tracker from the pause menu. The collectibles have to be found the old fashioned way as well; the map you could buy from the eStore only worked for the main game, so make sure to spam eagle vision at all times while in or out of missions to hopefully trigger them all on the map. The underground districts shouldn't pose a problem here, but if you are having trouble my best advice is run along the outside edge of the map, a few bicorns and chests are hidden along there.

Note: The co-op missions are only required to be played once each; getting all rewards is not necessary.

You need to not only complete the main tasks 100%, but also all the additional ones and collect everything. That is, what if the DLS had 100% synchronization.

For those who do not have the last 2 tasks of the Franciade open, you need to return to Paris and complete 1 investigation, which is indicated by a magnifying glass icon.

If someone is confused about where to take the quest “The Eye of the King,” then it should be taken not in the dungeon, but in the house in the basement.
