The StarCluster Engineer's Guide is an in-depth look at how spaceship systems work, looking at each system and subsystem in turn and examining them in much greater detail than the Starship Design Guide. In addition, systems which were part of packages before are broken out and discussed, as well as introducing new variants and totally new systems, such as the stealth system. Also discussed are the effects of varying the ratio of Matter to anti-matter for different purposes, spaceship hulls, sensor arrays, weapon systems, maneuvering systems, docking, hydroponic systems, HVAC, fingerprinting drives, transponders, the components and functions of a spaceship's shield systems, and much, much more. This guide is designed with the space engineer in mind!
This guide is also available as part of the StarCluster Technical Supplement #2. If you already have that supplement, you don't need to get this one.
