@VitaVitaAR: What I mean is that everything that had happened canonically in the Dead Space universe is still true for Isaac Clarke, but I've added on a bit of this and that to explain why his abilities are more powerful than they were in-game. To do that, I had to make things happen post DS3 (the most recent installment to the DSU) which would make it canon in a sense, but with more added on to it that takes place after every event ever mentioned, it also makes it AU.
