According to the ESRB, this game contains Blood and Gore, Strong Language, Violence
Parents, RLH contains a fair bit of blood and gore, some language, and some sexuality.
Survival-horror fans may find it worth a look due to the setting and story, but likely will become bored by the uninspired gameplay. I suggest The Thing (multiplatform) or Silent Hill (parts two and three are available for the PlayStation 2) for a more effective dose of survival-horror tension.
Fans of sci-fi might enjoy RLH for its plot and respectable acting (even if the script is rather cheesy at times).
Deaf and hard of hearing gamers will miss out on much of the dialogue due to the lack of subtitles, and much of the game relies on in-game audio cues
