TT Games has announced its Minecraft-like building game, Lego Worlds, is available to play now on Steam Early Access.

The game, which did not have a pre-release announcement or build up, is described on Steam as allowing players to "explore environments filled with adventure ... discover secrets and treasures ... create your own models."

Naturally, as an Early Access game, developer TT Games and publisher Warner Bros. Interactive have invited players to submit feedback.

"LEGO Worlds will be a fully open-world, creativity-driven game so we want to ensure that we provide it with the utmost care and attention as we expand on our ideas," Warner Bros. says.

"So much of this game will be about building and sharing and by sharing our plans with the community, we hope to incorporate their feedback and build an experience together that fans of Lego and this genre of video games can enjoy."

According to the Steam Early Access page, Lego Worlds will be in Early Access "through 2015 at which point we hope to have our full list of features in place."

"We'll evaluate a release candidate in early 2016," it continues, "but we won’t consider the game complete and ready for release until we believe our community feels we have delivered a great game."
