A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

War has raged under Calth long after the actions on the surface, protracted conflicts to slay entrenched Word Bearers throughout the planets depths carry on. It has been 4 years since Squad Acastus secured a teleportarium and routed the Word Bearers from their librarium outpost. Our story picks up with a Legion Moritat, Orestes, attempting to rescue Calth Defence Forces from being sacrificed by Word Bearer cultists. What’s New with Betrayal at Calth? Enjoy the planet Calth on our beautiful new title screen! ACT 3 is by far the biggest release so far with 6 new single player levels and 4 new un

We have a very important update coming this Friday that will affect all current owners of The Horus Heresy: Betrayal at Calth. But don't worry- it's a good thing for everyone! Here's what's going down: Price Reduction to $17.99 That's right, we're lowing the overall price of the game. Since we're in Early Access, we decided it would be best to reduce the price until Full Release. It's something that many members of our community have mentioned, and we listened. When the game is fully released the price will go back up to reflect the value of the content, but until that time it's $17.99. All Cu
