From publisher blurb:
After Gray Monday, the Republic has descended into a new Dark Age, ploughshares are being turned back into swords, and the jackals are feeding on the confusion. The desperate need for weapons of new militaries arising everywhere sees mundane machines strapped with outlandish weapons, flamboyant arena ’Mechs returning to the battlefield, and renowned manufacturers engaging in uncharacteristic experimental gambles. It is a seller’s market; anything goes and no price is too high. Caveat emptor—the dust will settle quicker on your new acquisition’s battlefield debut than on the transaction that got you there. You won’t have time for buyer’s remorse.
Experimental Technical Readout: Caveat Emptor samples production and prototype machines that have earnt infamy after Gray Monday as inefficient monstrosities sold to the highest bidder. Each unit featured in this book incorporates some of the new technologies that debuted in Tactical Operations (or quirks found in the BattleMech Manual)—now employed on battlefields of brush wars on former Republic worlds. Statistics and Record Sheets are included for 13 new advanced and experimental BattleMechs, ready for play in advanced BattleTech games.
