Hey everyone,

For many months now, we've been working on an upcoming major update, known as the "Hazmat update". In the last few weeks the whole team's been working on it exclusively, so the number of isolated fixes ready to release in the meantime was limited. Still, today we've accumulated enough of the fixes to constitute an in-between update.

Notable improvements:

Today's update mostly focuses on bug fixes, such as:

  • Fixed the camera tilt bug
  • Fixed VR belt points taking items when they shouldn't
  • Optimized item spawning
  • Alt-tab now pauses the game
  • Pause stops the sounds too

Progress on the upcoming Hazmat update:

Despite being called "Hazmat" (short for Hazardous Materials cargo), the update will include a lot more. We grew the scope, so its primary mission would be to reach a stable version - as if we were releasing Derail Valley for the first time. Apart from explosions, the main improvements will include the overall fidelity and game-play improvements (more goals, more challenges, better tutorial). This will involve a complete coupler rework, speed signs, new licenses, among many more additions. We will have dedicated news posts for each feature subset, as we near the update release.

At this point, most of the core features for the Hazmat update are near completion. About two weeks ago we started testing them and are now doing optimizations and general polish. That's the current status, but note that this will take a while. There is no release date estimate yet.

In the meantime we are likely to release a few more smaller bug fixing updates, such as this one!
