Great game design integrates live game operations to be successful

Dead Effect 2 – BadFly Interactive



BadFly Interactive are a small creative studio responsible for the acclaimed FPS ‘Dead Effect’. The studio is made up of developers with years of experience. The whole team has worked in the media and game industry for many years, participating in various AAA titles for the PC, Xbox, Playstation and currently also mobile devices.



BadFly gets to Gamedonia in search for an integral backend service that would be easy to plug into the game developed with Unity. This was of capital importance for Dead Effects 2, because it was already finished, all it lacked at that point were the backend functionalities to become a retail product. The main requirement of DE2 was a flexible platform that was adaptable to the game to give it the power to store user and game data in the cloud and a way to run server code. To top the fundamental needs for the live game, BadFly looked for additional services:

  • Push notifications: both programmed and on the fly.
  • Communication with the API: scalable and secure.
  • A reliable communication protocol.
  • User login credentials: silent, Facebook, Google+, Game center.
  • Avoiding the creation of fake accounts.



Having finished client development for Dead Effect 2 and the deadline for the release fast approaching, BadFly needed a partner that could adapt and find solutions to their specific needs. Gamedonia offered backup for the large anticipated quantities of users playing the game and the reliability to store heavy loads of data. Because DE2 can only be played when users are connected to the internet, saving game sessions in the server was a crucial safe-net when users lose connection, to allow them to progress in the game when connection is reestablished.

Last but not least, in-app purchases play an important role in the monetization and the balance of the game, thus getting protection against cheats and false purchases was a must.



Being built with security and to be flexible, Gamedonia was a good fit for BadFly from the start. The suitability of our scalable database solution was quickly confirmed, allowing the developers to host and manipulate game information reliably.

Gamedonia secure protocols of communications and store receipt verification proved satisfactory to avoid hacks on purchases. Although, some security reinforcements were applied to BadFly’s request on the user credential access avoiding account duplication for user over-validation.
Due to DE2 being an always online game, verification of the users connection status was mandatory. The design of Gamedonia’s call Gamedonia.isInternetConnectionAvailable verifies whether the user is connected to the game checking for activity between the client and the backend.

Gamedonia emphasizes security with 3 different protocols of data protection and validating all purchases data against the corresponding app stores. The HTTP protocol is known for its bi-directional encrypted communications. Gamedonia adds to that security implementing extra measures to further protect communications.
