Hello dear developers. I am the owner of the game Nuclear Winter 68 First Edition. I recently bought myself a PnP edition of the Nuclear Winter 68 Heart of Darkness 2nd Edition. And was unpleasantly surprised by the complete incompatibility of these two games. I very much hope for your understanding and sympathy, and I want to ask you that the owners of the old edition was given the opportunity to purchase the old edition of Heart of Darkness. First of all, I am interested in the old edition of the units. I want to ask you to provide me with a copy of the old edition units. I still have my purchase receipt. I can show it in personal correspondence. Sorry about my English.
