samuraigaiden: Maybe the devs can chip in and explain what this means.
I am curious about that as well. I wonder if it is just a poorly worded way of saying it is an alternate ending that was scrapped from the main game.
It refers to it as an extended ending scene not a DLC add on as people have been taking it as in the launch forum. I get this feeling it may be a separate video in the extras section of the game as opposed to actually part of the game it self? Some confirmation on this would be good.
Addendum:
A comment from someone on Steam some what confirming that it is not a DLC for an extended ending but more a little bit of historical add on like lore books.
"Its not the ending of the main game. The main game has an ending for the storyline. The video in the DLC is more of a "historical" record that bridges the world of Deep Descent with world of Archimedean Dynasty/Aquanox.
Calling it "extended ending" really isn't the term they should have used. "
