isn't this a cracked version? i eman you can put anything in the box and progress in game.
you mean C&C is like Dune 2
yeah sandworms you have two options. one is to kill them. the other one is to feed them.
if you want to kill them you have somehow make them follow your trike or somehting and when trike is on safe ground stard pounding the worm.
another solution is to get some cheap units (trikes or infantry) and feed them to the worm. once the worm eats enough it will dissapear. beware as there is usually more than one worm.
later in stage i suggest you to use carryall thing, because it will transport your haverster safe and quickly from and to your base.
