Yes the content is in the patch.... dont know why, maybe number of Bug fixes.
So to start off with, Dont expect to load the game and walk into the new content, It took me a good hour or two to figure it out using the internet too.
You Basically have to do the following in order
1, Kill Hydra.
2, Quite the game and load back in
3, Walk around the left side in the water right to the back where the golden crystal golem is. Kill him and free the duke person that spawns after killing the golem
(I saved and quit out and loaded back in again JUST INCASE, dont think its needed but got fedup of trecking back and forth to find out i was missing something)
4, Head to the Dukes Archive, In the first room with the Crystal Enemys, you will see a Golem, Kill him and get the broken Pendant.
How head back to the water where you killed Hydra, and run around the back where you killed the Golen to free that person,
And you will see a portal.
So anyway after all that, what do i think of the content.
Love it, sort of, I only killed two bosses at the moment,
And its not fun doing this with 4.8 Million souls haha

There is not much of a level before the second Boss.
You spawn into the Prepare to die part.
Run through the fog, Kill the boss.
Then run through the next section and run through a woods area(Takes 3 minutes to run) takes less than 10 minutes to kill everything and get to the next Boss.
Killed him and thats where i am now.
The area is like Dark Root Gardens, Very low FPS issues,
thought the game was going to crash at one point.
Met some guy on it last night and was co-oping with him on Skype.
Symon, Charlie,
GET ON THIS!!! Will be nice to chat to someone on Skype or something and play this mofo in co-op
Guy i was playing with last night had no mic.
Any of you fancy this later on?
