The next update will be coming towards the end of November.

We've updated the build today with our third major update: BASIC TRAINING! Read all about it here!

Our next update will be RPG ELEMENTS, arriving in October.

Today we've launched a new build that addresses some of the most pressing feedback we've heard since launching on Early Access. You can read about all the details in this devlog.

The next update with new features and content will be dropping in September! I'll update this post when we have an exact date! In the meantime, thank you all so much for your feedback, it's been really useful - keep it coming!

As the game is still in development (and in Alpha), you may encounter problems when playing. Some of them we already know about but haven't been able to fix for the current build. Sorry if you run into these problems! Please know they're on our list and we'll do our best to fix them soon.

General issues

• The game crashes on startup with certain USB or Bluetooth audio devices connected
  Workaround: if you get a crash on startup that includes the line "FSubmixEffectReverb::OnProcessAudio", try disabling or disconnecting any USB or Bluetooth audio devices and try starting the game with your computer's default audio device only
• Some users hear pops and crackles on certain audio tracks.
  Workaround: If you experience this, try lowering the "Maximum Audio Loops" slider in the Audio Options.
