There may be some small errors here and there, since I don't have perfect pitch. Plus, 
is not very often you play metalsongs on acoustic guitar.

Verse:
Gm
The saints are crippled
On this sinners' night
F                       Cm               Eb  F
Lost are the lambs with no guiding light

(same chords as above)
The walls come down like thunder
The rocks about to roll
It's The Arockalypse
Now bare your soul

Bridge:
Eb
All we need is lightning
     Gm
With power and might
F                             Eb
Striking down the prophets of false
Eb
As the moon is rising
Gm
Give us the sign
F                     D
Now let us rise up in awe

Refrain:
             Gm     F               Eb         Bb
Rock 'n roll angels bring that Hard Rock Hallelujah
Cm          Ab            Eb          F
 Demons and angels all in one have arrived
(same chords as above)
Rock 'n roll angels bring that Hard Rock Hallelujah
In God's creation supernatural high

(here's some crazy riff, check out the tabs if you want to learn it, it sounds kinda 
a 4x4 beats of F#m)

Verse:
The true believers
Thou shall be saved
Brothers and sisters keep strong in the faith

On the day of Rockoning
It's who dares, wins
You will see the jokers soon'll be the new kings

Bridge

Refrain
(there's another crazy riff after this refrain)

Break (or what you call it):
Gm
Wings on my back
Bb
I got horns on my head
Cm
My fangs are sharp
       Eb       F
And my eyes are red
Gm
Not quite an angel
    A
The one that fell
Bm                          C
Now choose to join us or go straight to Hell

F   Gm  Gm       Bb Bb      Cm 
          Eb F        D
             HARD      ROCK       HALLELUJA         x4
(after the D-chord, play the refrain a thousand times)
