The series was created as a joint effort between several people and groups. Matt Burch programmed all three games in their entirety except for the registration system and various libraries. He also devised and created the scenario for the first game. Ambrosia Software, headed by Andrew Welch, managed marketing, registration, and distribution, as well as providing several external libraries used by the games. Early test versions of the game went by the name 'Merc' (short for 'mercenary'). Peter Cartwright wrote the scenario for "EV Override" and the Australian company ATMOS created the scenario of "EV Nova"; both originated as plug-ins for the preceding games before being picked up by Ambrosia as sequels. The fighter pilot voices in the original game were provided by Patrick Delahanty. A plug-in of additional phrases was also created and later included as part of "EV Override".
