If you haven’t ever played the original Dark Souls and are interested in Dark Souls III, you can snag yourself a free digital copy of it by pre-ordering it for the Xbox One. The offer is good for both the standard edition and the deluxe edition (which also includes the season pass) of Dark Souls III.
Dark Souls isn’t currently backwards compatible on the Xbox One, but it is coming, presumably, sometime soon. If you own a Xbox 360 still, you can play it on there to hold you over until that happens. Or just pick up Dark Souls II: Scholar of the First Sin for the Xbox One. One way or another, if you can get over the initial hurdle of dying constantly, you’ve got some excellent options to hold you over until Dark Souls releases April 12th.
