Microsoft has announced that the free Fallout 3 bonus copy for Fallout 4 on Xbox One will be available only until February.
If you have Fallout 4 on Xbox One, or are planning to get your hands on it, you'll receive a free copy of Fallout 3 alongside via the upcoming Xbox One backwards-compatibility feature.
However, Microsoft has now revealed that there's an expiry date on that rather appealing offer.
Anyone looking to bag that free Fallout 3 copy should move quickly. The deal is only live until 6 February 2016, as spotted by GameSpot's keen eyes on the Xbox.com site.
"Through 8 February 2016, purchase Fallout 4 and receive Fallout 3 on Xbox 360. The code for Fallout 3 will be delivered to your Xbox message center in 7-10 days. Redeem your code on Xbox One or Xbox.com. Fallout 3 will be backward compatible, so you can play it on Xbox One starting 12 November."
Xbox One backwards compatibility launches tomorrow, 12 November, with a long list of 104 supported games.
Of course, Fallout 3 is just one of those supported.
