	* Oh. Oh, I see. This wasn't quite part of the plan.
	*
	* Looks like they won't let you take the Algorithm
	* without a fight. You'll need to carefully weave your
	* way through the guard drones.

	* I need you alive, after all.

	* fondly - but attack drones are so much easier to reason about
	* when they're not staring you in the face, I would imagine!
