In the Valley of Gods from Firewatch developer Campo Santo will not be launching this year as previously announced.

In a statement to Polygon, studio co-founder Jake Rodkin said that the 2019 release date was "optimistic" and that members of the team have been working on Valve projects since the company's acquisition of Campo Santo in April 2018.

Rodkin said that its developers have been helping out with the recently-revealed Half-Life: Alyx as well as auto chess release Dota Underlords.

"To fans looking forward to In the Valley of Gods, it’s probably clear that the optimistic '2019' at the end of the announcement trailer isn’t going to be accurate," Rodkin said.

"In the end, Valve Time makes fools of us all. But yes, developers from the former Campo Santo team have joined other projects at Valve, including Half-Life: Alyx. As you can imagine, our experience in the first-person adventure genre is pretty relevant. You hear a lot about how at Valve you can work on what you want. It turns out that’s true, and there’s a lot of work available. As we integrated ourselves into Valve it became clear there was a lot of valuable work to be done on Half-Life: Alyx. Some of us starting lending a hand, and have since become full-time on the project as it approaches launch. Similarly, some ex-Campos are working on Dota Underlords, some are on Steam, and so on. So to answer your question as of today, In the Valley of Gods development is on hold – but it certainly feels like a project people can and may return to. And when that happens, we’ll find an exciting way to let fans know."
