According to ESRB, this game contains: Animated Blood & Gore, Animated Violence
Parents should be on alert. Even the game itself opens with a title screen warning of grotesque and violent imagery. And while I didn't find any of the dialogue and violence to be over-the-top and gratuitous, the game is definetly for more mature eyes. As I write this review for Carrier, it is literally only a week before the release of Resident Evil—Code: Veronica.
It's probably a smart decision on the part of all survival-horror fans to wait and see if Veronica will be vastly superior. Yet regardless of the final verdict on Veronica, I think many will be pleasantly surprised by what Carrier offers to the genre.
I have no reservations about recommending Carrier to more hardcore fans that can't get enough of this style of gameplay.
I also think that more casual gamers new to the series will find the lighter degree of overall difficulty and short, but focused length of the game to be quite enjoyable.
