How do you install medieval 2 total war kingdoms

you just simply install it like you would anyother game or expantion pack.
it needs the same mod as medieval 2 total war so if the disk for kingdoms needed version 1.4 (like mine) then you need to upgrade m2tw. be sure that you have a graphics card because the battles are so laggy with 1.2 or above.
you'll need admintstratoral rights to upgrade m2tw which sucks so if i were you i would buy the games together, they usually give the same mods when selling together.

kingdoms totaly rocks! especialy the greek fire on crusader
