wrote about a couple of weeks ago, and made them available on my Free Stuff page. You can also get v1.0 here:
The Campaign For Alto Peru
Although they are designed for use with my Liberated HOTT variant, they should be easy enough to adapt for standard HOTT, DBA or other sets. If the Political Tokens are removed then they would work for a linear or ladder campaign with very little alteration.
If you give them a try I'd love to hear about it.
