The demo is being played a lot the past few weeks, so the current changes are focused on removing small annoyances that you tend to notice from time to time when playing more than a few minutes.
When placing a building there is now a visual indicator that shows the forward direction. This will make it more clear how the building needs to be turned to get it in the right orientation.
Builder turrets will stop firing when there are not enough resources.
Builder turrets will change targets when resources are not available for their current target.
Builder turrets will prioritize partially completed buildings when picking a target to build
Changing settings will now also make a click sound with the continuous settings (volume ect.)
More forward oriented 'first person camera preset' added to the spectator camera
Anti Missile projectiles no longer do significant damage on normal units.
Locked build items will have their cooldown reset of the unlock power threshold is not met anymore.
