From the back of the book: "In the year 3025, war rages across all of known space. The Successor Lords vie for supremacy over the entire Inner Sphere, each commanding a vast army of troops. At the forefront of these forces are BattleMechs, 12-meter tall humanoid juggernauts bristling with enough firepower to level a city block. Centuries of war have taken their toll, and 'Mechs have become scarce and valuable. The presence of these behemoths on the battlefield often spells the difference between victory and defeat! This revised edition of the original Technical Readout: 3025 features the most popular and powerful BattleMechs of the Succession Wars, as well as a selection of support vehicles, aerospace craft and rare Star League-era 'Mechs. Each of these war machines is illustrated in detail, accompanied by a description of its history and capabilities and complete BattleTech game statistics. Fully compatible with the BattleTech boxed game." Note: For legal reasons, this revision of Technical Readout: 3025 removed the infamous "Unseen" (the entire entry, not just the artwork) and replaced them with 3025-era variants from Technical Readout: 2750.
