Gamers on Xbox One will soon have a new way to express their creativity. ROBLOX, an MMO that lets players create and share games, is coming to Xbox One on December 3rd.

Roblox is getting cross-platform play between the Xbox One, the PC, and smartphones, starting later this week.

Console owners can now swell the ranks of 300,000 existing game makers on Roblox, as long as they have an Xbox One.

Xbox One is getting Roblox, the inventive build-your-own-game online experience. It’s free to download, and it will come with 20 curated levels and modes built by fans.

The new Xbox One app will allow Roblox content creators to release their games on multiple platforms simultaneously without having to worry about porting the code to each new system.
