Then this little phrase here. The timing on this is a little weird.
I tried to separate it to make sense.
It goes in a group of 2, then 1, then 3, then 1, then 2.
Then hold on the F.

E|--------------------------------|
B|--------------------------------|
G|--------------------------------|
D|--------------------------------|
A|-4-3---2---1-0------------------|
E|---------------4---3---2-1------|

Then hit an F5 chord and go back to the intro riff, but leave off the first A# (13).

For the part where he sings "Out of the depths of the sea,"
the note that's being played is an F, (I'm pretty sure, although it might be an E)
so you can hit whatever you want there.
I usually play an F5 chord:

E|-----------------|
B|-----------------|
G|-----------------|
D|3----------------|
A|3----------------|
E|1----------------|


Then back to the second part of the intro.
After this a couple more times, (listen to find out)
the little shuffle thing is:
E|-----------------------|
B|-----------------------|
G|-----------------------|
D|-6br-------6br---------|
A|-----7-7-5-----7-5-7---|
E|---------------------0-|
