Just to reassure some of you guyz about the multiple endings available and their achievements.

Contrary to what you may have read somewhere else, IT IS absolutely possible to achieve all the different endings in a single playthrough.

There are only two requirements :

1_ Having uncover all the Drawing Man's memories in order to use the door to his shrine.
It appears near the white tree in the Convergence Zone once the 7th shard is freed.

2_ YOU MUST NOT go through that door.
Unlock the "Shattering" ending, then "Carcosa", and "The Watcher". Go back each time you unlocked one.
ONCE AND ONLY AFTER achieving those endings will you go through the door in the Convergence Zone.
Why ? Because contrary to the other endings, you won't be able to go back to the Convergence.


Hope that helped !

And please, let me know if I missed something / get something wrong.

Have fun !
