=====================================================================
 
Hi, I'm ArtifactMage and this is my bare-bones walkthrough for 999. 
By bare-bones, I mean, I won't be listing controls or characters or 
holding your hand through this game. This guide is just to help you 
get through the endings of your choice as quickly as possible.
 
In general, please examine all evidence you get and make yourself 
familiar with the room before you look at the guide. 
Some of my instructions might seem confusing if you don't know your 
surroundingsor haven't talked to the other characters about certain 
pieces of evidence.
 
Let's get started, shall we?
