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.

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.

Roblox is a massively multiplayer online (MMO) game and development platform which allows users to create whatever they want.

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.
