Experimental Technical Readout: ComStar samples the custom and prototype designs that were developed in the testing labs and top-secret proving grounds of ComStar's scattered military. Each design featured in this book incorporates some of the latest technologies developed by the realms of the Inner Sphere as the war against the Word of Blake waged on. These technologies--first described in Tactical Operations--have only begun to achieve widespread production, but each has been prototyped and rushed to the field for their desperate consumers. Statistics and Record Sheets are included for 13 new experimental BattleMechs, vehicles, aerospace units.
