Skeptics Apocalypse is the debut album by American heavy metal band Agent Steel. It was recorded in Los Angeles, California and mastered at Frankort Wayne Studios in Miami, Florida by Tom Coyne from December 1984 to February 1985. The album was released by Combat Records in June 1985 and reissued in 1998 by Century Media Records.
The bonus tracks on the 1998 reissue contains an updated version of "(The Calling)" titled "Calling 98 for Skeptics" and the never before released song "The Unexpected" in live format, both of which are of unknown origin. The latter can be seen and heard on the Mad Locust Risinghome video. A second remastered version, released in 2008, contains the two songs, plus a cover version of the Judas Priest song "The Ripper", which was originally featured on the Mad Locust Rising EP.
"144,000 Gone" and "Taken by Force" are re-recordings of songs John Cyriis had previously cut as demos with his pre-Agent Steel outfit Sceptre in 1983. The Sceptre version of "Taken by Force" appears on Metal Massacre IV.
