To go along with your Day One Edition of the Xbox One, Microsoft is releasing some of the launch titles with Day One Editions as well. These Day One editions are available only as pre-orders, so if you try to buy one, Day One, you won’t be able to (makes sense).
For Forza Motorsports 5, you’ll receive the Day One Car Pack DLC which includes the Lamborghini, Audi, and Ford with a Day One theme and custom tuning package.
Dead Rising 3’s Day One Edition will net you a Classic Frank West outfit, slugger weapon, extra attacks and extra attributes. Also included is a Chuck Greene outfit and Paddle Saw.
Ryse: Son of Rome will receive the Ruins multiplayer map and the Legionnaire’s Trust Exclusive Sword. Player that own the Ruins map will be able to invite their friends to join them on the exclusive map.
