I've been working on a sci-fi world for the past few weeks, and (being a man of science) got carried away and wrote up tech specs on all of the tech I plan on introducing over the course of the story arcs. (I limited myself to two) How much of this detail is usable and when would be a good time to explain how these devices function? (mostly slug-throwers, but some lasers and gizmos here and there) For reference the part pf the story I've chosen to focus on first takes place in the mid 2070's, China controls most of the US and the rest has been admitted into Canada as provinces, when war breaks out between the South Asian Socialist Union and Canada/NATO. Laser weapons see their first combat use early in the war. Our story follows members of a regiment of infantry created to manage intelligence and research.
