This prototype represents a marked improvement in the development of the project. It has some new mechanics implemented and old ones refined, as well as some new units and new artwork by Tim Grant. This is also the first time that we’ve integrated voice acting into the game, with Epona Schweer playing the main character Eve. This prototype was developed with the help of The Digital Kitchen Funding Program by Metro Screen and Screen NSW.

Future Directions

This prototype puts us in good stead to implement more complex game types like conquest and the ultimate goal of a DotA-mode. To further realise the spirit of the Protocol E control scheme, other features on the cards are:

  • Custom unit composition and formations
  • Customisable unit parameters like bravery, minimum attack distance, max chase range, etc.
  • Customisable theat ratings and target priorities.
