According to ESRB, this game contains: Blood and Gore, Intense Violence, Partial Nudity, and Strong Language
Parents will want to steer children away. The main character uses profanity several times throughout the game, and although it's used appropriately, it's not exactly something that parents probably want young ones exposed to. However, language is a trivial concern when compared to the game's level of violence. Alien guns are used to dispatch extraterrestrials that come in several varieties, each more misshapen and gooey than the last. There is a strong biological element in the level design (certain doors look exactly like shaved vaginas), and some of the graphics and situations can be fairly intense. The M rating is well deserved here, so take heed.enter content here.
FPS fans will find a fairly straightforward adventure spiced up by creative level designs and use of gravity. Negotiating some of the environments is a little mind bending, although the linear nature of progress always keeps the game moving forward. However, don't see linearity as a negative in this case. If the game gave players more freedom, it would be far too easy to become hopelessly lost in the maze of up, down, in portals, and out.
Deaf and Hard of Hearing gamers will most likely not be satisfied. There is a subtitle option in the menu, but the text appears on-screen in a microscopically unreadable size that's impossible to see clearly, let alone in the middle of battle. Also, some of the voice work for the game's main bad guy (girl, actually) does not have subtitles for some reason, so players making it to the end of the game will only get half of the conversation. It's not a large omission, but a very annoying one. Additionally, hearing noises of nearby monsters and the sounds of incoming gunfire can be crucial. The game's resurrection feature helps lessen the significance of hearing these auditory cues, but it's still worth noting.
