If you transfer your save from PS3/Xbox 360 to PS4/Xbox One you will be treated to a whole bunch of new items, missions, and events. This content is exclusive to transferred data players only.
Here is a list of the new content
New Events & Rewards
Encounter new events happening all across the world, and complete the challenges they present to unlock exclusive new vehicles like the menacing Imponte Duke O’Death and that veritable GTA classic bird of flight, the Dodo seaplane.
As Michael, follow a trail of cryptic clues to unravel a grisly murder mystery. Put the clues together and you’ll unlock two Noir Style Filters, which will give your Story Mode gameplay and Snapmatic photos the feel of a gritty old school crime classic.
Weapons: The Rail Gun & Hatchet
Obliterate your adversaries with the high-powered, high-velocity Rail Gun. This piece of experimental military technology also has its own set of Shooting Range Challenges at your local Ammu-Nation shooting range. Or hack and slash foes up close and personal with the brutal Hatchet melee weapon.
Wildlife Photography Challenge
There are new species of animals across Los Santos and Blaine County, and the LS Tourist Board needs someone to document them. As Franklin, catalog unique animal species scattered across the map to unlock the special Kraken Sub.
Stock Car Races
Win a series of new Stock Car Races to earn unique custom Muscle Cars adorned with logos from some of the companies that made this country great.
A mysterious street artist is tagging walls all across town with his simian-inspired silhouettes. Track down and photograph them all to earn new monkey outfits (available to all players) and a special Go Go Monkey Blista exclusively for returning players.
New Vehicles and More
Grind up the Los Santos freeways (and over anybody in your path) with the Cheval Marshall monster truck and take to the skies in a faster and more maneuverable Blimp, compliments of Xero Gas.
