UPDATE: Bandai Namco's official announcement suggests that Dark Souls may not be backward compatible with Xbox One quite as soon as initially thought, confirming that it'll be playable on the console "later".
"For a limited time, gamers who digitally pre-order DARK SOULS III on the Xbox One Store will receive the original DARK SOULS; playable now on Xbox 360, or on Xbox One later via Backward Compatibility," Bandai Namco said. "The code for DARK SOULS will be delivered to their Xbox message center in 7-10 days."
VideoGamer.com has contacted Bandai Namco for further clarification on the backwards compatibility release timing.
ORIGINAL STORY: The original Dark Souls will soon be backwards compatible with Xbox One and available for free with all digital pre-orders of Dark Souls 3, Microsoft has revealed.
As spotted by Reddit, the Australian Xbox Store states that download codes for the original Dark Souls will be delivered to pre-order customers within 7-10 days of purchasing, suggesting the game could be made backward compatible within the next week.
Microsoft has yet to formally announce Dark Souls for Xbox One backwards compatibility or confirm when exactly it will be available on the service. The deal is not yet live on the UK Xbox Store.
Dark Souls 3 launches in the UK on PS4, Xbox One and PC on April 12. The latest backwards compatible Xbox 360 title was released on Xbox One earlier today.
