In October 1985, the band recorded an EP titled Mad Locust Rising, which was released in January 1986. Bassist George Robb was fired after the recordings and was replaced by Letchen Grey bassist, Michael Zaputil, shortly after. In March 1986, Agent Steel entered the studio once again to record their second album Unstoppable Force. The recordings came to a halt when the band went to perform at the Aardschok Dag Festival in Eindhoven in April 1986. In May 1986, they toured Europe with Anthrax and Overkill before returning to the studio to finish the recordings in June 1986. The album's release was then delayed due to complications with the cover artwork. An early 1987 release was then planned. In November 1986, Capitol Records expressed interest in signing the band, who had recently signed Megadeth. The band's management demanded more money, in which the label agreed to, with a stipulation that the band would have to wait until the new year to release the album, and with the acquisition of new department budgets. John Cyriis and Chuck Profus moved to Florida for various reasons, while the rest of the members remained in California. In January 1987, Capitol Records withdrew from the offer due being unable to secure required industry-standard performance and surety bonds, due to the seemingly unreliable nature of Cyriis and the band's abrupt line-up changes. Unstoppable Force was released in March 1987 by Combat Records instead. Cyriis and Profus were then joined by guitarists James Murphy and Jay Weslord, and bassist Richard Bateman. The new line-up performed shows in Europe with Nuclear Assault in June 1987, one of them being at the Hammersmith Apollo, in which their final performance can be seen on the 1989 home video Mad Locust Rising. In 1988 the band disbanded, as their record label, Combat Records, put them on suspension. This suspension lasted for as long as the band's contract with the label lasted — about three years or so. In an interview, Cyriis stated his version as to why Agent Steel was disbanded in 1988: "....Agent Steel was buried alive by Combat Records, who put the band on suspension for no legitimate, justifiable reason. Why they did so, remains a mystery to this very day..." First reformation (1998–2009) In 1998, guitarists Juan Garcia and Bernie Versailles reformed Agent Steel without Cyriis' consent, featuring returning members Chuck Profus and Michael Zaputil, and new vocalist
