The End in 30 minutes.. what's going on here

[Jimmy]

Ok so I just "finished" Amnesia, but I barely had half an hour of gameplay?!
I started in a room with an oil lamp, came to a room with one monster, climbed up a ladder, crawled through a small corridor and came out above a library.
Found some stuff in said library and snuck into a hidden door behind a bookshelf.
Then I ran through some rooms flooded with water and avoided some monsters again, arrived in a room where I was almost killed Star Wars garbage compactor style but survived in the end and could leave up a starwell.

Fade to black, credits, The End.
What am I missing here?

[GLaDOS]

Justine probably?

[Skulker_S]

sounds like you didn't launch the base game.
go to the launcher and press the right button this time

[GLaDOS]

No. That sounds exactly like justine...

Messaggio originale di GLaDOS:

No. That sounds exactly like justine...

yes, and justine isn't the base game, it's kind of a addon/alternate story...

[Andrew]

I lol'd

[Jimmy]

haha ok thanks for this, turns out I am an idiot. I am used to buttons being on the right side, did not even read the whole menu properly.

[Skulker_S]

happend to me at the first lauch to, but i noticed it right away
nice job on beating justine without having the experience of playing through the dark descent btw :D

[GLaDOS]

Yes. But Justine is more a hit-and-run game... so it is not that hard if you are lucky...
