Rockstar Games has released a free Grand Theft Auto Online update that lets you create your own deathmatches and races. To get the tools, just play the game and download the automatic update that became available today.
Once you download the update, you can access the Deathmatch and Race Creator Beta in the Online tab of the pause screen. Here you'll see options to create a new deathmatch or race, or load and edit one you've already begun. Before you try your hand at creation, you can play through a tutorial that shows you the ropes.
