Various minor fixes and a new feature: a programmable Teleport that lets you start a level at a specific location. Nothing comes for free though-it costs 1 star :)
Additionally, a new Kamikaze mode: if you haven’t unlocked the BOMBER and don’t want to search for all 5 parts, you can sacrifice your cyber-miners to destroy the reactor (within the story).
They will get the job done—they are obedient—but they won’t survive the circuit overload and will be lost permanently.
The choice is yours: suicide missions or unlocking the BOMBER.
