Fans of Half-Life have launched ‘Project Borealis’, an attempt to create Half-Life 2: Episode 3 as described by Half-Life writer Marc Laidlaw, in his release notes last month.

They announced their first update on Reddit, showing off concept artwork and in-game 3D assets. The Half-Life fans have stated they have around 60 people working on the project with developer backgrounds using the Unreal Engine.

The Reddit post’s author did not mention how they intended to be allowed to legally release the game. Future updates and a tech demo were promised for the next post.
