Last club night, Dave Wood ran a play test of his Look, Sarge, No Charts: Science Fiction scenario fo Historicon 2018. The rules have been under development, on and off, for a few years, and some aspects are starting to shape up. In particular the cyber phase is working well. I am not quite happy with the spotting rules; the issue of sensors and signatures makes things a little complicated for my tastes.
We haven’t gotten past the spotting stuff to start on RF spotting and RF-guided munitions.
