The approach or philosophy to developing the game was described as with immense emphasis on community feedback. In fact, CPL might be hiring pro-gamers to advise directly in conjunction with the games development. As described in the press release, there will be two parts to the game. The 1v1 game type and the 5v5. The reason I would describe them as parts is because they will have almost completely different physics and game play attributes. Although it wasn't directly implied, I can gather that the 1v1 mode will be based mostly on the Quake franchise, while 5v5 on Counter-Strike. The engine will be based on the Quake3 server-client model, using Quake3 'netcode', and some sort of , 'id Software' rendering technology. They haven't announced which, but possibly completely new. We also know that CPL has already licensed the Quake 3 engine.
