Rust.

With the world in it's final death throes, two former soldiers can rely only upon one another to survive. Noah (stricken with advance stages of a virulent blood disease known as R.U.S.T.) worsens every day. Aurora, despite being young and impulsive, has come to look upon Noah as her guardian and she desperately wants to save him. The two must face the remains of a forgotten city, a spanning wasteland, and Ravagers as they search for a cure.
