If you pre-order the new Doom from id Software on Xbox One, you'll get a special bonus (for a limited time): the original '90s classics Doom and Doom 2.
The offer is listed on the Xbox.com product listing for Doom, which is out on May 13. The listing notes that Xbox Live Arcade redemption codes will be sent to pre-order buyers in an Xbox message within 7-10 days.
All Doom pre-orders also include the "Demon Multiplayer Pack," which comes with an assortment of cosmetic enhancements and six Hack Modules, a multiplayer aid that gives you a boost of some kind for a single match.
Both Doom and Doom II were previously released on Xbox Live Arcade for Xbox 360. Both games were later added to the list of backward compatible Xbox 360 titles that work on Xbox One -- which means you don't need to go plug in your old 360 if you nab this bonus.
