The Bloody Guns requires version 2.2 or later of the JACL interpreter to play. This interpreter can be downloaded for Linux or Windows from either of the follow places: http://www.ifarchive.org/indexes/if-archiveXprogrammingXjacl.html http://sourceforge.net/project/showfiles.php?group_id=13258 There is currently no Mac port of the JACL interpreter, although the Linux source for the GlkTerm/ ncurses version should be straight forward to compile. The file bloodyguns.blorb must be kept in the same directory as the game file for it to be found when playing the game. Please send any questions or comments to stuart@animats.net
