Brian Werking and bassist Chris Wiser formed the Maryland band back in 1986 and released a demo in the autumn of 1987. Guitarist Ted Hartz was also in the band. Another demo followed in the spring of 1989. The band split up in 1990 due to a lack of interest. Two years later Chris reformed the band and and released a demo in the spring of 1993. In the meanwhile Werking had reformed the band as a 'solo' act and was recording a parallel Exmortis' songs for a 7" release on Rage Records! While Chris dissolved his version of Exmortis in this period due to a conflict with guitarist Chewka, several months later he reformed the parallel Exmortis and aside from writing new songs compiled older songs for a tape and CD release.

Brian Werking and a reformed Exmortis began working on a new demo in 2005.
Exmortis reformed in 2011 and signed with Xtreem Music for the release of a new EP and full-length album. The EP was called Resurrection... Book Of The Dead and out on the 20th of December. It was recorded by Brian Werking at Shockwerks Audio in Tampa, Florida.
