Nordues, Space Ape Games and Aardman Animations will join Cities: Skylines developer Colossal Order as speakers at the Unite Europe conference in Amsterdam next month.
That's in addition to a keynote address from Unity Technologies CEO John Riccitiello, who will be addressing the company's European community for the first time since he took the role last year.
As Unity's official conference, a good portion of the session schedule is taken up by talks from the company's employees, describing every aspect of its increasingly diverse business and its roadmap for the year ahead.
However, Unity also welcomes contributions from its vast audience, with Aardman Animations, Wooga, Nordeus, Tinybuild, Modern Dream, framebunker and Game Insight all contributing this year.
Perhaps the most intriguing new addition, however, is a dedicated virtual reality track. At last year's conference, in Seattle, VR was a relatively muted presence in the schedule, though what was there was provocative and interesting - as these comments from Cloudhead Games' Denny Unger prove.
You can see the full schedule on the Unite Europe website. The event will be held at Amsterdam's Westergasfbriek on June 23 and 24.
