The GOG.com library continues to expand, with the retailer announcing today a new distribution deal with Bethesda Softworks to start packing the publisher's old-school library. To celebrate a number of Bethesda games going DRM-free, GOG.com is offering up a weekend of discounted bundles, as well as a freebie offer.

Users can pick up an Elder Scrolls three-pack that includes The Elder Scrolls III: Morrowind GOTY Edition, The Elder Scrolls Adventures: Redguard, and The Elder Scrolls: Battlespire for 33 percent off. An id Software three-pack that includes Quake (with Mission Packs 1 and 2), The Ultimate Doom, and Doom II + Final Doom is also available for 33 percent off. There's also a Fallout three-pack that includes the first two Fallout games and Fallout Tactics for 66 percent off.

Picking up any of the above or any individual Bethesda game will also include The Elder Scrolls: Arena and The Elder Scrolls II: Daggerfall for free. The sale will run for the next seven days.
