Those who upgrade to the new-gen version of Grand Theft Auto V will get access to exclusive missions, vehicles, and more.

The content will only be available to those who already own a last-gen copy of the game and buy it again on Xbox One, PlayStation 4, or Windows PC.

The extra content includes:

New events that unlock exclusive new vehicles like the Imponte Duke O’Death and the Dodo seaplane

A Murder Mystery mission that unlocks two noir style filters, which give Story Mode gameplay and Snapmatic photos the feel of a gritty old school crime classic

A high-powered, high-velocity Rail Gun and a Hatchet melee weapon

A new Wildlife Photography Challenge, and a Monkey Mosaics photography mission that unlocks a special Go Go Monkey Blista

A series of new Stock Car Races that unlock unique custom Muscle Cars

New Vehicles including a Cheval Marshall monster truck and a faster and more maneuverable Blimp

There will also be extra content for all who buy the game on new-gen or PC, including a fleet of classic GTA vehicles and “a few more surprises we've got planned that you’ll have to discover for yourself come game day,” said Rockstar.

GTA Online players on last-gen consoles will be able to transfer their characters and progression to new-gen or PC once. Any Special Edition or Collector’s Edition content will also transfer across, and will also be available to earn and acquire with in-game cash.

The same goes for any Jobs you’ve published in GTA Online using the Creator tool. However, Leaderboards, Snapmatics, Playlists and bookmarks are unique to each console generation and so will not carry over.

Those who pre-order the game will receive a bonus of GTA$1M: $500k for Story Mode and $500k for use in Grand Theft Auto Online.

These upgrades are not coming to last-gen versions of the game.

Finally, GTA Online on the new systems will support 30 players not just in Free Roam but in competitive modes as well, unless the Job you’re playing has been designed to be set to a specifically lower player max.

“We look forward to seeing what unique matches the community can create for a vastly increased number of players,” said Rockstar.
