From the campaign:
Time to announce the much requested expansion forces!
The five initial forces will be unlocked at £9,500 so they should hopefully help push us up to getting the big book released! I'm also trying to finalise the contents, so now is the chance to have your say (although I may well ignore your suggestions…).
The expansion forces will be priced at £16 each, or you can get any two for £30. You can also swap out any of the starter forces from the Emperor pledge for two expansion forces, giving you a lot more choices to make if you are at that level!
