 Ethnic Cleansing was developed by members of the National Alliance , an American white supremacist organization , and published by Resistance Records , its subsidiary record label that specializes in white power music . It was developed for Microsoft Windows personal computers using Eclipse Entertainment 's open @-@ source game engine Genesis3D along with the Reality Factory development kit . The source code was not substantially changed from the original . Instead , the developers simply plugged in images and sounds that they had created in freely available editing programs .
