The Elder Scrolls: Arena is 25 years old today, and to celebrate the big birthday Bethesda is giving away The Elder Scrolls 3: Morrowind. Just pop over to bethesda.net, log in to the site (or sign up if you need to) and then—wait!—do not hit the "Redeem Now" button yet!
I know, that seems like the obvious thing to do but first you want to take note of, or perhaps even select and copy, the "TES25TH-MORROWIND" code, without the quotes. Now hit the redemption button, put the code into the field, click where you're told, and the game will be added to your account, accessible through the Bethesda launcher.
The previous Elder Scrolls games, Arena and Daggerfall, are also free (and have been for awhile now), but Morrowind is the one that put the series, and Bethesda, on the map. It's big, bold, and beautiful, unconstrained by the bug-ridden wonkery of the games that came before it or the comfortable conventions of the ones that followed, and it is free. Today only, though, so get on with it.
This is not the only thing Bethesda is doing to mark the 25th anniversary of The Elder Scrolls: There's also a free-play event coming this weekend to The Elder Scrolls Online, some anniversary loot in The Elder Scrolls Legends card game, and new in-game content for The Elder Scrolls 5: Skyrim.
