The movie was based off of a comic. I believe it was an independent web comic.

It wasn’t fully animated, the characters were like cut-outs, like the animated version of Dante’s Inferno by Sandow Birk and Marcus Sanders.

I saw it on Hulu between 2011-2014.

The main plot is that aliens, thought to be demons, came to Earth, and enslaved humanity. People believe the biblical apocalypse has happened.

A teenage boy is wondering the wasteland trying to survive.

If I remember right, the movie starts with him living with a priest of some kind.

It was very grim, dark, and violent.

One scene that sticks out, the main character gets raped/beaten by a female alien/demon, that has a cyborg penis.

I hope this is enough info, it’s been almost 10 years since I watched it, and I’ve been looking for it for the last 3 years now.

Thank you for your time!
