Rockstar has released a title update for Grand Theft Auto Online that adds 'beta' versions of its new Deathmatch & Race Creators tools.
The new functionality lets players create their own custom deathmatches and race scenarios with, according to Rockstar, "the same tools our own game design and development teams use".
Custom matches can be made for Deathmatch, Team Deathmatch, Race, GTA Race and Rally Race modes, accessible from the Online tab of the pause menu.
Rockstar offers a more detailed description of the tools in a new blog post.
In a statement earlier this week, the developer teased GTA 5 players with the promise of "substantial" single-player story expansions in 2014.
"For those ready to jump back into the story of Grand Theft Auto V, we have big plans for substantial additions in 2014 continuing Michael, Franklin and Trevor's action, mayhem and unexpected adventures in Southern San Andreas," it said.
