BioShock creator Ken Levine has revealed that his next game, which has not yet even been announced, will run on Epic Games’ Unreal Engine 4. He confirmed the detail this week on Twitter.

This is not all that surprising, given that Levine’s previous games–BioShock, BioShock 2, and BioShock Infinite–all ran on iterations of Epic’s technology. The new project, however, is his first using Unreal Engine 4, the latest version of the popular toolset.

Other upcoming games that use Unreal Engine 4–which is now available free to anyone–include Microsoft’s new Xbox One Gears of War, Dead Island 2, and Cliff Bleszinski’s Bluestreak, among others.

After Irrational Games closed in February 2013, Levine–and a small number of others–remained on-board to work on a “smaller, more entrepreneurial” project for Take-Two. Meanwhile, the BioShock series is now being developed by 2K Games in California. While no new entries in the series have been announced, management says the franchise still has lots of room to grow commercially and creatively.

In January, Levine offered more details about his new project and studio, both of which do not have names yet. The game is sci-fi-, targeting PC, won’t be revealed at E3, and isn’t anything like a Telltale Games title. Check out this post for a roundup of everything Levine said about the game.
