Backstory

Most invaders break things. The Gun-Turner does not break things. The Gun-Turner interviews them. It reaches the first defence on your field, stops, looks at it with the calm of a recruiter who has seen every résumé, and makes an offer the tower cannot refuse: join the flock, or keep being a tower. Every tower has accepted so far. The offer is apparently very good.

It does not destroy your guns. It recruits them. The Gatling stops firing at chickens and starts hatching them — a converted defence is now a chicken spawner, and the chickens it spawns are not grateful. They are numerous. That is the entire problem with the Gun-Turner’s plan: it is very good at converting one tower, and then it hatches, and then everyone is chickens.

The farm has a protocol for this, written in the margin of a manual and underlined three times: kill it fast. Not the tower it recruited — that one is already gone — the Gun-Turner itself, before it reaches a second defence. One interview is a setback. Two is a coup.
