Question from what i have heard there is extra content a new henchman and such in the game, if you install the world domination starter kit.
I have downloaded that part in GOG galaxy, however so far i haven´t got any new henchmen option or research option.
I have tried to verify and uninstall re-install the game even started up a new game.
Am i missing something or what?

As far as i remember
I.If you didn't change anything the new installation with the Kit was installed inside the old folder, so the old shortcuts at the destok are useless.

II,It should have a new start file instead of the old Evil Genius, so you have to be careful wich one you use
