The Rox conversion for the Commodore 64 further iterates from the original game for the VIC-20. In this title Jeff Minter pays tribute to the classic arcade game Missile Command.
One of the earliest titles developed by Jeff Minter, this pre-Llamasoft title was sold by dk'tronics along with the Deflex V in multi-game cassette's for the Vic-20. An enhanced version would later be release for the 8K VIC-20 as Rox III.
