Rockstar has detailed the exclusive content available to players who upgrade from the last-gen versions to PS4, Xbox One or PC.
The highlight of the content are some new activities, including a murder mystery with Michael, stock car racing and a wildlife photography contest.
They’ll also be several exclusive vehicles, with series favourite Dodo seaplane making an appearance alongside the Imponte Duke O’Death, a new blimp and the Cheval Marshall monster truck.
And because GTAV just didn’t have enough weapons, a rail gun and a hatchet have been dropped in for good measure.
All players, new and old, will also find a fleet of classic GTA cars to play with, and anyone who pre-orders will receive $1 million in game split 50-50 between story mode and online.
