In the year 2005, five young musicians from Oberhausen decide to form a band that played aggressive, groovy metal, and so One Bullet Left came to be. The band quickly succeeded in gaining fame on the local level, resulting in an increased level of motivation on behalf of the band members. A four-track EP entitled "Invisible Fleshwounds" was recorded in Denmark with the help of former Hatesphere singer Jacob Bredahl. The EP was released in 2007 and received mostly positive reviews from various fanzines.

One Bullet Left pride themselves on their reputation as a live band, having shared the stage with the likes of Kreator, Volbeat, Hatesphere, Paradise Lost, Caliban, The Black Dahlia Murder, Dry Kill Logic, and Maroon to name a few. After two line-up changes, the band decided to make the necessary steps to record a full-length album by visiting Kohlekeller Studios in Hessen. After much hard work and deliberation, "Armageddon Sunrise" was eventually released on February 25, 2010 with the help of Darkest Hour Music/Twilight Distribution.
