Bethesda Softworks decided to dip into the backcatalog today, bringing two of its highly-lauded open-world adventure classics to Valve’s Steam service: Morrowind and Oblivion, both from The Elder Scrolls franchise. A standard and deluxe edition of Oblivion is being offered, the latter of which includes all downloadable content released to date.

Also making its digital debut is horror title Call of Cthulhu: Dark Corners of the Earth. For a limited time only, all Bethesda published titles are running for 20 percent off their original purchase price, with the exception of Fallout 3.
