I really wouldn't be surprised if they release some sort of DLC if this does well enough, which I'm sure will piss some people off.
I don't know if anyone here played the Dead Space game on mobile, but I remember that game being pretty good, and pretty intense in some parts.
Are a lot of mobile games cash grab casual gamer crap? Yeah they are, but doesn't mean someone can excel beyond those expectations. Just don't go in expecting a AAA level of experience.
What would be cool is if they could somehow support mobile vr devices such as GearVR or Google Daydream.
