Kingdom essential?

[Panzerwu]

Just out of curiosity, is Kingdoms expansion required for Stainless steel?

I saw the blood gore and detail in this mod, i ever so want to play it...

However I only own the M2TW, no expansion.

Does that mean I can't use the mod?

Yes, you need the Kingdoms expansion to play Stainless Steel. However, you only need one Kingdoms Campaign installed (so you can just pick your favorite if you want to save space).

I think an older versio of SS, 5.1 or 4.1, does not require kingdoms

[Caesar Clivus]

4.1 doesn't require kingdoms. Kingdoms only costs a few dollars now so you might as well buy it.
