okay, to use the autoquest(!squest on),
buy lots of pages that fit your level,
create a private room with a password,
change the game mode to quest,
then type in the command(!squest on) while you're still in the game lobby.
it does the quest for you.
i don't know if it works 100% though..
because everytime the portal opens on the first round,
gunz crashes on me.
but hope it works for you!
