Grendel Games uses proprietary technology to create nearly all of its (serious) games. The 'Chameleon' engine combines graphics, audio, animation and physics to create an engaging experience for the player. Furthermore, because the engine is completely platform independent, a game that is developed for PC can easily be run on a Wii, Xbox 360 or Playstation 3.

The in-house editor and tools environment 'Atlas' enables artists to develop content and logic in-game without the help of programmers. Since all technology is developed in-house, there's an in-depth knowledge about each and every feature, allowing the programmers to focus on creating interesting gameplay, instead of wasting time on figuring out third party APIs.
