Immortalis is the 14th studio album by American thrash metal band Overkill. It was released in 2007 on Bodog Records. It is a pun of "Immortal15", and was preceded by Killbox 13 and ReliXIV (with the Roman XIV for 14).[citation needed] The album sold over 2,800 copies in its first week of release in the U.S[3] and as of 2009, Immortalis sold over 15,000 copies in the U.S.[4]
This was also the first Overkill studio album to include drummer Ron Lipnicki, who joined the band shortly after the release of its predecessor ReliXIV (2005).
