High Guard Rules
High Guard Rules brings Classic Traveller's Book 5: High Guard starship construction and combat rules to the web.
Ship Designer walks you through building a warship from the keel up — hull, jump and maneuver drives, power plant, computer, weapons, and screens — following the Book 5 construction sequence, with every calculation (tonnage, energy points, agility, cost) handled for you automatically.
Combat Arena lets you pit your designed ships against another player, or fly solo against an AI opponent — resolving the full Book 5 ship-to-ship combat sequence round by round: Battle Formation, Initiative, Range, Pre-Combat Decisions (break-off, emergency agility, surrender), Combat, Damage, Breakthrough Combat, Pursuit, and a Terminal step for boarding, repair, and crew transfer.
Ship Library keeps your saved designs on hand, and Meeting Room is where you find another player and start a battle.
Whether you're building a fleet, sparring with the AI, or working through a firefight against another captain, this site handles the math so you can focus on the tactics.
