Unity has demonstrated a Unity Engine game running inside of an Unreal Engine game, marking a step in the direction of Epic Games CEO Tim Sweeney's vision for an interconnected gaming ecosystem.

The demonstration took place this week at the Unite Seoul keynote, where Unity also announced the next version of its game engine. Unity's goal with the project, in partnership with Epic, is to allow Unity developers to publish their games in Fortnite.
