I'm playing Dead Space 3 and I'm at Chapter 6 ( after completing an optional side mission)
It's classic Dead Space through and through ( I was worried that Co-Op would ruin it) It's still the scariest game out there with second to none combat and I can't forget the sound!
The Necromorphs are extremely creepy(and ferocious) in their mummified forms, and the fact that later in the game they actually infected different alien species for you to battle is just more icing on an already delicious cake!
The only thing I'm still somewhat on the fence about is the weapon crafting. I appreciate the Dev's wanting to do this and the possibilities are indeed endless but it's pretty daunting at first....
It is getting easier and will definitely draw players into multiple playthroughs to create the ultimate Necromorph killing machine!
