Hello people of the Subnautica Wiki. I just had a problem where the game isn't working. When I open the game, there is a black screen. I found a way how to fix that, and the steps are very easy. First, open Steam (And login if you have to), then go to your game library. After, right click, or left click if you do, then you see a list next to your cursor. Then go to the bottom of the list, then press "Properties". After, go to "Local Files", and press "Verify Intergrity Of Game Files". It may take a while for it to fix it. Then it says that a # of files are blah blah blah. Then, it is fixed. I hope this is very helpful to the people who love Subnautica! <3
