Panzerfaust are summoned by Yngve (W.E.B., Memorain, Christfuck, Dizziness, ex-Acherontas) and Auren (ex-Nyne, ex-W.E.B.). A couple of songs are written, but never recorded.

The band splits up, after Auren leaves for Sweden and Yngve joins the army.

2007:
Yngve reforms the band under the name Mortuus Sum and begins composing and recording the first demo, which is not yet released.

2010:
After a long time as a one man’s band, Yngve recruits Jim Havok (Chained And Desperate), bassist and long time friend to play bass and handle the vocals for the band. Almost at the same time, Morrigan joins as the band’s lyricist. Recordings of “Promo 2011” are finally started.

2011:
“Promo 2011” is finally released in May, in digital format and the band begins writing songs for an upcoming split EP with the Greek thrash/death metal band Blasphemahus. The songs for the first full length album are also composed, but not yet recorded.
In August, Vaelor (Odin’s Court, ex-Diablery, ex-Mors In Tabula), joined the band as a guitarist.

2012:
Jim Havok decides to leave the band in February. He left in good terms due to limited free time, as he lives in a different city than the rest of the band. At the same time, Tartarus (Odin’s Court, ex-Nipenthis) joined the band to handle guitars and bass, along with Vaelor.
Not a lot of time passed and in April, Tartarus leaves due to restricted time and heavy schedule at his job. Morrigan also leaves for personal reasons. Just as before, Jim Havok returns to handle the bass once again, after Yngve’s decision to keep Mortuus Sum as a studio band.
In May, Ikteros (Funeral Storm, Aphorism, Mors In Tabula, Nano Infect) joines as the vocalist and Banshee joines as the band’s lyricist.
On October 3rd, a split EP with Funeral Storm, entitled “Inverted God”, is released in digital format and is available for free download.

As in April 8th, Ikteros is no longer our vocalist, due to personal reasons.
