GOG.com is dedicated to providing enthusiasts with a source for popular retro games, from a time when gameplay was at the forefront. GOG’s catalog includes hundreds of relatively inexpensive Good Old Games, most from just $5.99 to $9.99. Signing up for a free account gives new members instant access to six free games; Dragonsphere, Tyrian 2000, Lure of the Temptress, Beneath a Steel Sky, Ultima IV Quest of the Avatar and Teen Agent. Anyone who enjoys playing games should definitely have a look around GOG.com.
GOG.com is currently offering the legendary FPS, Duke Nukem 3D, absolutely free. Available for both Windows and Mac, BUT it is only free for a short time… until Friday, December 14, at 14.59 GMT.
Duke Nukem 3D: Atomic Edition, the legendary FPS in which the Earth’s greatest hero provides a steady flow of bullets and badass one-liners, is available on GOG.com, for the low price of one smile, for the next 48 hours. That’s not all. For the first time in history, this supreme space-alien slaughter simulation is also available on Mac!
