The 20th Anniversary Edition of Countdown To Extinction will be released on November 6th as a 2CD lift-top box and digitally. Countdown To Extinction's new commemorative edition pairs the remastered original album with a 1992 concert, recorded live at San Francisco's Cow Palace, which has never before been released in its entirety. The concert audio has been newly remixed for this release. The physical and digital versions both include a booklet with a new liner notes essay by music journalist Kory Grow, and the 2CD box also contains a 24" x 36" poster and four collectible postcards.

Megadeth will perform the album in its entirety on their North American Countdown To Extinction 20th Anniversary Tour this November and December.
