I have finished my 1st playthrough and accummulated over 56000 Nano Catalyst points. I know this because the only module that unlocked during the entire playthrough Threat Tracer (level 1). Everything else remained locked. I played at Soldier difficulty (to get used to the games and feel out the bugs I have been reading about).

My research has found very little on unlocking modiules, just on what they are, what they do and how to get the points for them (universally kill the aliens and pick up the points before they expire - anyone know how long they stay viable for pickup?) So it is kind of annoying that I could have unlock almost all the modules with the points I have recovered so far. Is there something in particular in addition to killing the aliens to unlock the modules?

I am about to start my 2nd playthrough at Veteran difficulty. Hopefully it will be more successful with the Nanomodules.


EDIT: I am an idiot. Found out what I was doing wrong. The nanomodule screen layout was not very intuitive.
