Note this is an as-is version for general interest, please don't ask me why none of the gameplay is finished yet :)Call of Red Mountain uses the assets from Morrowind by Bethesda Game Studios (2002).In order to play this game you must have acquired those files in some manner, they are not distributed with this game engine.You will need to copy the Morrowind installation folder onto your device, this can be up to 1.2Gb or more so you will need plenty of sdcard space.You can copy it to any location that is accessible from your computer's file explorer.When you first start up Call of Red Mountain you will be asked to select the Morrowind.esm file that is located in that game installation folder on your device.
