Exciting stuff. Really looking forward to it.
As an old editor/writing instructor, allow me to offer a few suggestions that you're probably already aware of. The first text block has some dropped text -- I suggest the following phrasing:
LnLTS is a solo system that enables players to play the scenarios that come with the games as well as those created with our Battle Generator. But we wanted to reach beyond that and provide one solitaire package that works across the entire Lock ‘n Load Tactical series for all past, present, and future games.
Also, enable may be a better word choice than allow throughout, because the game isn't granting you permission, it's enabling you to play solo... and have a blast.
