This is an extremely rare version of this early Epyx game, in fact so rare that I can find to reference to its existence anywhere! Most likely it was released like this in Europe only, and only for the Commodore PET computer (obviously). Having a game published by more than one company was almost unheard of back in the 70s so it is unclear exactly under what terms this was published. If any one has seen any other Epyx games like this let me know!
