Further update.
Finally finished the transition between chapters 2 and 3.
This is (hopefully) the most difficult one - just 2 left now.
It required a complete rebuild of a 2-minute segment of the audio, then rescoring and then sorting out the transition into and out of the Kuill-IG reprogram scene.
Here is the 5 minute segment.
All these are looking very promising. I had wondered how you would work in the IG-11 flashback bits. Where will the rest of that fit?
