Fate Averted! Cleared “Ghost Trick”
Missable achievements.
These achievements are chapter related and can be miss.
In case you do miss or fail some of the requirements, you can either start chapter from beginning or from previous safe.
You might need to do it before “times up” screen pops.
Chapter 5
Mystery of the secret room.
In order to do this, you need to prevent Lynne’s death without failing ones.
Chapter 9
Careful of the Crimson Light
Probably hardest one. You need to lead Detective Jowd from hes cell to top without getting notice.
You can and should safe between hiding places so you don’t have to start from the beginning if you are seen.
Chapter 10
Too Much Medicine
Same as chapter 5. You need to safe justice ministers life without failing ones.
Chapter 13
Captive on the Roof
You need to capture crazy lady with chandelier on your second try. First one will all ways fail.
Chapter 14
Extraordinary Failure
In this one you need to fail of saving park guardians life. To do this you need to close the lid of garbage trunk before dropping the ball.
Chapter 15
Red Light! Green Light!
In this one you need to prevent either one or both ( no confirmation on this one) deaths without failing ones.
Final Chapter
First Appearance of Life
To do this you need to send sweet potato to the middle like normally, fire it up and swamp with Mino (large egg statue). Instead of continuing this swamp with lamp post, exit ghost world and let Mino fall.
Secrets
A Curious Soul
Move from object to object 444 times with Sissel. Will probably unlock during story but if not, just move back and forward.
Jumping Poltergeist!
Perform 444 tricks with Sissel. Doesn’t need to be different. If you don’t haven’t yet near the end, just do same trick over and over again. I personally got this in chapter 4 by moving desk lamp back and forward.
Same, Same!
Same idea as previous one, but swamp 44 things using Missile. Doesn’t need to be different, you can swamp same things over and over.
Others. (Work in progress.) Details might change or have been guessed.
