According to this eurogamer article its coming at UE5 Full release
‘The Matrix Awakens’ main character - IO - aren’t really a part of Warner Bros IP, so this entire segment of the demo including the assets will be given away with the full release of Unreal Engine 5 in the spring of next year, along with tutorials for developers in how to build their own open worlds.
“I’m really excited to see what the community is going to do with this, right?” says Jeff Farris. “I mean one of the big goals with the engine itself is to just facilitate creators. What’s the friction and how do we make it easy? You look at the tech like Lumen and Nanite, and that stuff really helps with that, but just releasing this to the community and letting people do what they’re going to do with it is amazing.”’
