Is the combat modes solo variant still planned to be published later in the Paper Wars magazine?
Do you have an estimate when this will be available?
No estimate yet on the Paper Wars follow-up; sometime in 2017 for sure. There already is a solo system for using the combat modes, but the Paper Wars version will be more elaborate and (hopefully) more realistic. I've played it many times using my own "best choices" for combat modes and I love the feel of the system even without special solitaire rules.
