While everyone else who wants to gain early access to the Duke Nukem Forever demo will have to purchase a copy of Borderlands Game of the Year Edition, Steam users who bought the original game appear to have gotten a surprise invite to the party.
Kotaku's posted some images of Duke Nukem Forever First Access Club codes that have appeared in the site's Borderlands CD key for Steam.
Publisher 2K said last Tuesday that gamers who buy Borderlands Game Of The Year - out this Friday - will gain access to a "wealth of goodies", including an early demo of Duke Nukem Forever.
The game and demo have yet to be given firm release dates, but the latter's promised to arrive "prior to the retail launch" of DNF next year.
Have you checked your account for a code, Steam players?
Gearbox boss Randy Pitchford said last week that Duke Nukem Forever is packed with sex, swearing and violence - and "dances on the line of decency".
