Hi guys. Well, I was looking into the demo files and found a Judas with pulse cannons instead of the rocket. I found him in 2 locations. He can be encountered under gui-fstpersn-machines-adc4trch and gui-machines-(blue-green-red-yellow)-adc4trch. What is funny is that if you cut these files and paste them over the full machines' files, the judas' pictures will be with the pulse but he will still have the rocket. Look into that...
And I also found different sounds, listen to the characters' sounds in the demo and compare to the full version's. I prefer the demo's sounds more. The commander sounds WAY better in the demo too.
