This is a RTS file for Duke3d 1.1. It may work for ROTT and version 1.0 of Duke, but may not. To use just goto setup then modem game, then change RTS file. Then click on First. Then have fun and listen to the great British Monty Phython sounds! Thank you, Michael. E-Mail at 100660,2373 Web Site at: http://ourworld.compuserve.com/homepages/Jam_Software
