Experimental Techical Readout: Corporations samples the custom and prototype designs that are still going through their shakedown trials in the corporate research sites throughout the BattleTech universe. 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 thunders on. These technologies—first described in Tactical Operations—have yet to face their first actions in real combat, but each has been tailored for an eventual debut on battlefields yet to come. Statistics and Record Sheets are included for 13 new experimental BattleMechs, vehicles and aerospace units presented in this book, ready for play in advanced BattleTech games.
