The very last DOS REBEL free for everybody.
No other information is given other than it was released in January 2004, 4 months after the release of REBEL 12 for Windows. I assume it's the DOS mirror version of REBEL 12 for Windows tuned for human play rather than for playing against computers although the default REBEL.ENG settings suggest otherwise. I really can't remember.
There is a little glitch during the welcome screen, the program is complaining the tournament book isn't installed. You can safely ignore this message because the tournament really IS installed.
In 1980 I gave the program the name REBEL because (in the very beginning) it often did things I never ordered it to do and I felt it rebelled against his master. What could be more convincing to repeat that behaviour in the very last version?
Download Rebel 12 and install it under D-Fend Reloaded, a Windows environment to run old DOS games smoothly and user friendly.
