The sandworms that appear (by carryall) every 4 minutes are neutral. They even attack the units from player 1. They´re meant to work as a random factor in the map, like "something else the players need to be aware of if they want to succeed". That´s the best solution I could find to have them appear randomly (the other option was including house Fremen, but that would be confusing and if, by accident, the player is randomed as Fremen, he would auto-lose the map). Also, if anyone plays house Fremen, he´s not going to be allied with the sandworms; they still attack house Fremen´s units. (Now, if only the sandworms would have a random behavior as well; e.g. not just standing where they spawned, but moving from there, and eating a random number of units before disappearing...) Despite finding the directory where the saved files and maps are kept, I still haven´t been able to find the .cfg file with unit and building stats and tech tree (not even on the game directory). Any idea where it could be? I´m using windows 7 64bit, by the way. One thing that bothers me about polishing the game for multiplayer is how different it could become, compared to the original game.
