For information about the Shell, please see How to enable the XCOM developer shell. The Shell becomes part of the User Interface (UI) of the Main Menu.There are two primary developer features available: the Shell and the Console. It may be found in the 'Misc.' section of that mod's download page. The Long War mod team has made available such a patch mod that re-enables the Console in EW. The modding tools UPK Utils and UPK-Modder provide the mechanisms for implementing such 'simulated native functions'. However, recent investigations into the UPK File Format have determined how to convert a 'native function' into a 'simulated native function', which permits alterations.
Enemy Within disabled both the Shell and the Console with a native function.
