We Happy Few

There are 34 notes scattered across all three Acts. You can check your menu to view all of the notes except for "Alien Glossary."

One thing to keep in mind, if you pick up a note and then accidentally go on Holiday, you will need to re-pick that note up each time as the game doesn't auto-save when Notes are collected.

Author's Note: I personally made that mistake with Note #29 (you will collect that note many times while trying for "Helter Smelter"). However, even though I neglected to re-pick the note up (and it was therefore missing from my journal), when I collected the 34th note, the achievement unlocked. So if you make the same mistake, you also may get lucky and not need to replay the game.
