the game specific code are in two different folders and a third folder contain shared code, allowing communication between the game specific code and the engine. This third folder is named shared and the one containing the engine is named engine. the name of the folder containing the game specific code is often the name of the game but not always. In the Cube 2: Sauerbraten source code, the one of Sauerbraten is named fpsgame and the one of Eisenstern (the RPG embryo that come with most releases of Cube 2: Sauerbraten) is named rpggame. Alongside these folders, there are other folders, containing libraries used by the engine, the game(s) or both. This does not prevent engine modifications. Blood Frontier then Red Eclipse (before the version 2.0 of Red Eclipse) used modded versions of the Cube 2 Engine. A part of the features of these modified versions, such as the rain particles effect, were later added to the official version of the engine.

This engine actually share its name with the game it was made for, unlike its predecessors (the Cube Engine was made for Cube and the Cube 2 Engine was made for Cube 2: Sauerbraten).
