Tiberian Sun: A Player's Guide
Please find below links to both parts of TS: A Player's Guide v3 by Mole40k. This guide is intended for new and improving players seeking to find easy ways to improve their general game-play. Though the guide was written a good number of years ago now, it is still fairly relevant (even if the writing could be much improved!). If there is demand for it, I shall look at revising and creating an updated version later in the year.
Enjoy.
