Darksiders: Salvation

This story takes place before fury arrives on earth and after death made there sacrifice or before. And when war returned 2 years after that.

Humanity was never suppose to be apart of the war, nor were they ready and as a result there world became a battleground, cities plummeted, tsunamis swept through all the nations, trillions died and numbers dropped to a handful.

Now the world is overrun by demons, the undead, angels that cant go back home, heaven and hell at each other's throats with humanity right in the middle of it.
Now humans are coming back but changed, more horrible more grotesque, but one came back different then the others.

One with no memory aside From fractures and his name

One with a very strange and powerful arm.
