"What do you mean, 'unstoppable'? You are better trained, better equipped, and you've got them completely outnumbered!"

I tried to make this always bring in new enemies, but sometimes it gets carried away describing what happened to the last ones. If that happens, you'll have to tell it "I move deeper into the base" or show off your idle animation or something, and it should generate the next opponents.

Your persona, if you have one set, has an effect on how things are described. It embellishes your actions by design, integrating your dialogue into them, but it's not supposed to act on your behalf or make you say things you didn't. You can tell it your high level approach (e.g., "I draw my sword and fight Steve") and watch it go. Think about it like a video game where your basic joystick and action button inputs become cool-looking combos. If you want to get deep into description, it should handle that too, though if you do, what comes out can be quite florid.
