We wanted to use the holiday and the sale to announce our rough timeline for Xen. We are currently targeting a summer 2017 release. We will keep you up to date on our progress and we plan to show off some media as we finish developing Xen to give everyone a glimpse at what we are working on.

Why so Long?
We can't overemphasize how much work it was to get the game on Steam. Most of our effort before launching was put into porting to the retail engine and getting the game to work better than it did in the mod. Since release, the team has been focused on developing Xen. We even planned our updates to have features that would help improve the earthbound levels and Xen (for example CSM).

We want to do Xen the justice it deserves, and have it be the definitive climax to the Half-Life 1 story. To do this we have completely redesigned and expanded the Xen levels to what we think Valve would have done without the limitations of the time
