It is one of the most popular mods for Medieval 2, but is surpassed in popularity by Third Age: Total War. It combines bug fixes, many small mods, changes to AI and AI armies, more provinces, graphical improvements and many other campaign and battle map changes in a package aimed at providing a much greater challenge and more enjoyable gameplay. Stainless Steel was first started as a mod for Medieval 2: Total War ( v4.1 and lower), but it switched over to Kingdoms after the expansion was released.
