If you extract zod.tar.gz to /opt/zod it should already be executable. 'sudo chmod +x zod' in any case and run with: ./zod -l map_list.txt -n zlover -t red -b blue -r 800x480 for fullscreen or ./zod -l map_list.txt -n zlover -t red -b blue -r 800x400 -w for windowed mode. Removing '-b blue' will start the game with no AI so you can get accustomed to the interface.
