Had another go at Atomfall and made some progress, which is satisfying. Then I decided to head back to the army captain and tell him what I had discovered. The conversation went roughly like this:
Me: Hey Cap, just back from that dangerous mission you wanted me to do!
Captain: Were you responsible for the mass prison break and our key prisoner getting away?
Me: …Yes?
Captain: Guards!
*muffled gunshots* *sound of me diving into a flowerbed as all hell breaks loose*
So, I might have not made quite such great progress after all. Hey ho.
