Me too, but I didn't script them. It's one of those things we didn't have time for.
What I did do was script a mini-adventure which acts like one. It pulls you through a short story not unlike things you may have read or seen, and introduces various systems as you go. It was originally going to be used as an intro or trailer but realised it would serve a better purpose as a training sortie.
My writing is a bit cheesy, you can blame me for and not the actors, poor things, I'm sure they were groaning too.
