The final update before the steam wargame fest includes a spectator camera with some options to control it in the settings. When in a mission pick the cube from your arm and the settings will appear. On the second tab of the settings the spectator camera can be enabled and its follow properties set.
On the first settings tab the audio volume has now been split in music, SFX and UI. Reducing the UI and Music volume when recording with spectator camera could result in better clips.
When new objectives are discovered during a mission there are now some audio and visual hints alerting you to this. So its easier to know when to check your arm for extra objectives.
