The modification station is key for upgrades in Subnautica: Below Zero. This video, complete with coordinates, will show you where to get the modification station so that you have what you need to make that cool... underwater fire knife?
If you haven’t been able to find the mod station fragments, you’re in the right place. I’ll show you where to go to get it.
We start out at the shore of the Delta Station Island and make our way uphill to our location where you can scan the station and a bunch of other goodies. Oh, and there's only one modification station "fragment" so you just need to scan this one piece. Ready to go? Awesome!
