No, really.    Someone wrote an Ingress manual a long time ago in the style of Sun Tzu’s Art of War.    You can find it here.

It’s pretty far outdated and probably abandoned by the author.    That said, it is extremely well written, feels exactly like reading Sun Tzu.  Makes me think, perhaps it’s time for me to take on a project like updating it ?

Of course, that would require less real life, and peeling myself away from Marvel Heroes.
