Indeed, Mercy.
I've been playing Subnautica recently. It's a lot of fun, despite my irrational fear of deep water. (literally, like the only thing that scares the shit out of me, haha) It's still in early access and has a lot of work to go, but despite this, it's pretty remarkable as it stands. If anyone plays it, don't make my mistake, put your fire extinguisher in storage never to be seen again unless you're using it to shoot around in the water, as it stands, there is no other fire. I hucked it around with me everywhere, expecting a fire on a wreck or especially on the Aurora, but I finally decided to look it up, and you only ever can put out the original fire in the beginning. Haha...
Also, play experimental version. Besides the fish now respawning on it (your ocean begins to look barren unless you personally re-stock it later, and even then...), there is a lot of stuff that gets changed. If I knew what I know now, I would have made my game on experimental to begin with, but I would normally avoid unstable builds, this game is an exception. Plus it aids development.
Another pro-tip for anyone beginning, build 5 pipes under equipment as soon as possible. You don't have to rush or anything, but the sooner the better. Take the pipes, and connect them horizontally 1 after another as close to the surface as you can, all the way around your lifepod, so that the last pipe connects to the first. You can do it with just the 5 pipes, no need to make extra. Sometimes the lifepod floats away, it gets hit by fish or something supposedly and can end up very far from the safe shallows. Mine has never moved after I did this to it.
