The game was written using a commercial game engine (esenthel). Maybe a day I will discuss why I choosed esenthel over many other game engines...
Most of my work now is to improve the AI behavior, actually I started implementing an advanced FSM (finite state machine) for AIs and team AI.
Here is a demo level from the game. ( video quality is low due to compression, the FPS was equal to 15 images/sec due to Fraps capture)
