Immortalis is the 15th studio album by American thrash metal band Overkill. The title of the album follows a pattern that has occurred on the last three albums, all of which had the numeric album number in the title: Killbox 13 was the 13th album, ReliXIV was the 14th album, and Immortalis, as if as it was spelled Immortal15, is the 15th album.
* On the original CD track listing - track 8, Chaly Get Your Gun was misprinted as
'Chalie Get Your Gun', which in turn has lead to further misinterpretation as 'Charlie'. .
