Core, Manticore Game's free platform and community for video game players and creators, is now in open alpha after two years of development. The "digital playground" lets people create their own ...

'Core' is a game that allows players to create their own intricate games within it, share them online, and play online. It's in open alpha now.

Core is a 3D multiplayer game creator, as well as a platform for distributing and playing those games—sort of like Fortnite Creative, but without a big battle royale game layered on top of it.

Manticore Games is enabling NFTs in its Core metaverse platform, where users can create and host their own multiplayer games.

Core is a free, PC-based game development tool, similar to PS4 game Dreams and Fortnite creative, that aims to make game creation more accessible, much like YouTube and Twitch did for video.

That's allowed players to create full Dungeons & Dragons adventures in the space of a couple weeks rather than years. Core's Survival Jam challenges creators to build their own survival game.

In 2020, Core launched in open alpha for PC players, allowing them to dive into the game's many portals. But now, the game is out on the Epic Games Store in early access.

Fortnite developer Epic Games is leading a $15 million investment in Manticore Games, which develops the game creation tool Core.
