There doesn't seem to be much information at all about how they work. Website says:
"The Pinpointer enhances the accuracy of your radar towers for the entire team. You only need to build 3 facilities on each map.
Use them to improve the targeting of your artillery."
Does having more than 3 make them better with diminishing returns? What's the difference between 1 2 and 3 pinpoints exactly?
Does this ONLY apply to artillery? What kind of artillery? Buildings? Or any units with artillery-like weapons too?
Would love if the website or game has more detail on how this works. I think it would also help a lot of players understand what they do and therefore build them. It's rare to see players build them.
