A question about a book...

[Mattiah]

Hi guys, I'm writing a book base on the videogame SOMA.
But I have some questions... I mean, I need to know if I can publish that book. Cause I'm afraid to fall into the copyright abyss. Yes, because...

My book, named "The Afterdeath" (in english, the book is in italian for now), is a sci-fi novel about a guy called William Duck. This guy is doing some research in an agency called LSDU (in english: LSCD), an underground place where people study death and what could the humanity find after it. William is doing those research for his dead father, Christopher Duck, who has already worked down there.

So, William finds out that a mysterious guy is getting in William's way to stop him for some reason. This guy, you will found out later, was thinking about a machine able to explore the cosmos. He wants to do this to...

Take ARK back. Yes, ARK, the machine in SOMA where all people, once dead, find themselves inside this thing.

So, I ipotized that ARK, after a couple of years, crashes on the Sun.
And so that guy was trying to create a robot able, as I said before, to reach where ARK is, because he thinks that ARK is still in function on the moon. But that experiment will never see the light, because nobody supported the guy. So, after that, I never mentioned ARK again.

And it isn't that important for the story, I mean, it was an example for saying that this guy is doing experiments about machines and the space.

So, the question is...
Will I get reported for publishing this book, though I credit our lord Frictional Games and their work?

Edit: Okay, so... To be sure of my actions, maybe I might change some things such as ARK's name, but I don't know if I can use its story (life after death and the launch to space).
