Completion & New Game+
The one-playthrough requirements (Mycophile, Behind Every Crate Man…) are the common blockers — collect as you go. From Oblivion requires starting the Ex Oblivione NG+ mode.

|---|---|---|
| Sterilizer | Defeat three nightmares in Akeley Hospital (Ch. 3). | 50G / Gold |
| Mycophile | Listen to every Mushroom Jack radio broadcast in one playthrough. | 50G / Gold |
| Behind Every Crate Man… | Unlock every E.R.C. (Emergency Relief) Crate in one playthrough, excluding DLC crates. | 50G / Gold |
| What Dreams are Made Of | Obtain all Talents. | 50G / Gold |
| From Oblivion | Read all the writings that weren't there before — the new lore documents in the Ex Oblivione New Game+ mode. | 50G / Gold |
| For Her | Unlock all other 22 achievements/trophies. | 90G / Platinum |
Efficient platinum route
- Play the story while opening every E.R.C. Crate and activating every radio (Mushroom Jack broadcasts) you find — both sets must be completed within a single playthrough. Use the 13-crate and Activator Pen checklist, plus the 10-radio Mushroom Jack checklist.
- Complete each optional investigation when you reach its location — the eight codes and solutions are all in puzzle solutions.
- Spend Dream Essence toward all Talents (What Dreams are Made Of).
- Finish the story, then mop up From Oblivion in New Game+ — the new writings only appear in Ex Oblivione. Their exact route is in the Ex Oblivione documents guide.
