Your Warp Drives Await! A core expansion to Traveller, High Guard enables players to design, build, and fly spacecraft of all types found throughout the galaxy, and includes rules to modify existing ships, design high performance space superiority flyers, and construct the largest capital ships to travel the space lanes. High Guard also presents new approaches to handling spacecraft operations, from engaging in vicious boarding actions and spacecraft security, to accessing technologies seen in science fiction settings beyond the Third Imperium.
