Converted to the Atari ST by the author of the original Archimedes version, Jonathan Griffiths, Conqueror is a 3D tank combat game that uses a similar view to David Braben‘s Zarch. In fact, it uses the same graphics routines as Zarch, because Braben gave them to Griffiths.
Conqueror was published by Superior Software Ltd. (in the UK) and Rainbow Arts Software GmbH (in Europe), in 1989.
