Adds Demolisher riding! Ever wanted to use a big worm as a protective shell while you work on your factory?
Use it as a means of cliff destruction?
Exotic taxi?
Dune cosplay?
Would it be possible to make other worms attack the controlled worm if it invades neighbor territories? After all they are quite territorial beings... They don't have to necessarily kill each other, just aggro each other and become temporarily out of control. Or maybe just block one worm from entering another worm's territory?
