Night vision device allows to see better at night time. It can be installed on semi-modern tanks where Thermal Vision is unavailable. The most common use of night vision is night time navigation when lack of lighting makes successful fights almost impossible. Despite being a bonus in night time fights it is expensive to upgrade. Thermal vision is better than since it helps detect the heat of the tank. It was first deployed in 19a along with the night vision and tank battles
First appear: 19-alpha.
Night vision and the day/night cycle is not currently not available for update 2.0 due to the lag it creates.
