Officially called Low-Tech Companion 2: Weapons and Warriors (2010) this expands on the already-encyclopedic information on TL0-4 warfare in GURPS Low-Tech. It adds:
- History. A concise rundown of how fighting evolved from the days of stone axes to the era of pike, shot, and cannon.
- Weapon and Armor Design. Rules for customizing and resizing melee weapons, shields, and armor to suit almost any purpose.
- Equipment Damage. Battles are hard on gear. Gamers after ultimate realism can track each item's state of repair down to the last Hit Point.
- Fortresses. A look everything from hasty ditches to walled cities . . . along with huge cannon and giant siege towers for defeating them!
- Transportation. Practical guidelines for getting infantry, cavalry, and naval forces from A to B.
- Warships. Vehicle stats for early naval vessels, from penteconters to frigates.
