Grand Theft Auto Online launches on October 1st. However, GTA5's multiplayer will debut with a limited number of modes. When it goes live, you'll be able to enjoy the open world with up to 16 players. You'll also be able to take on various jobs and missions. You'll also be able to race and play various sports, including tennis, golf, and base jumping.
Additional features will be introduced as the game matures. For example, co-op heist missions will be introduced within "the first few weeks of Grand Theft Auto Online." In addition, GTA Online will eventually add Capture the Flag mode and "The Beach Bum Pack," which adds over 300 new items into the game--including 4 vehicles and 2 weapons.
The Content Creator is also scheduled for after launch. With this tool, you'll be able to create and publish your own deathmatch battles and races.
According to Rockstar's official blog, "all of these updates will be free." And while none of these expansions are dated, Rockstar tells fans that "we will probably add some extra stuff as well." Rockstar also confirmed microtransactions, saying "if you're the completely instant gratification type, you can choose to buy denominations of GTA$".
