How do you bring all the new Kingdoms units into one campaign?

[Kiki52]

Has anyone done it? How do you do it? Maybe a mod that uses the Kingdoms executable where you can have Apaches versus Tutons versus KoJ versus Ireland or something like that in a single campaign. All the balancing/building tweaking later, that can take a while.

Any help would be greatly appreciated thanks.

As far as I'm aware, you can't use all the knew kingdoms units together, but you can use each campaign's unit against the ME2 units. Simple start a custom battle, and set the time period to "all"
