This is a pretty simplistic game - Kill zombies, Survive, Have fun in a SIMULATION. I'm not quite sure why the OP thinks that the slaughter of zombies is a bad thing... Anything is possible until proven not to be - and if a zombie apocalypse ever were to occur... I don't think hugging the zombies will increase your survival rate...............................................................Anyhow, L4D2 is just a simple shooter with unrealistic depictions of violence - Shotguns and melee weapons do not actually work in the ways portrayed in so many games like this. Coming from a family of hunters I can tell you a shotgun does in no way, blow half of a body off. Nor can a hatchet cleave you in two. Just a fun little stress reliever - and in no way should be considered a serious approach to a disease riddled creature ( Running from the zombies - good --- Shooting them in the head - Good --- Using melee weapons and letting them beat you up - Terrible idea )

A overall very violent game full of blood and gore and kill everything and anything that comes at you is its message.

This game, though fun, is excessively violent and gory. But, on the other hand, there is a function to take off all the gore. This game encourages teamwork, but that is because it is just to survive. I have played online, and chances are you'll run into either a foul-mouthed teenager or a 30-year old pedophile. This game is so violent, I truthfully don't think I should be allowed to have it. There is a chainsaw, and when you use it, blood goes ALL over the screen! Disgusting! So, yeah. If your kid is under 13 years old don't, i say DO NOT let him/her get this game.

The best zombie/shooter game I ever played. It is so fun. The weapon choice is better than the first game. The storylines are better than the first one. There is minor cursing and no sex. Overall the best game!

I think its got allot of violance so probebly 10 and up. but safty isnt a prob but they ude guns and that would be the part where u need a mature kid maybe. and educational because u work together also known as team work. the game is very complicated but once u get the hang of it its easy. I say parents or gurdians get it for your kid if he/she is mature and if there not then if they really want it have a talk with him or her about how to be mature or how to act when they come accross an.....um..... an issue then they will know what to do. so choosey moms choose l4d 2.

love it but very gorey

if your kids want to play it because i dont think that zombies are going to take over the world and there is only going to be 4 people thet survived. but to me its a horrible game over all

I like it, it's a fun game and it isn't that bad, some swearing isnt bad people have heard that before. Blod is removable but it still is voilent

This game is great! The main reason this game is rated m is blood. there is ALOT of blood in this game. you can shoot off heads, blow a hole in a zombie. the only reason an 11 year old can play it is because there zombies and you can turn off the blood in the options menu. when you turn the blood off it turn off all the gore... so you can't blow off heads and stuff but there is still some blood. there isn't too much language but there is a little. including non frequent b***h sh*t, g*d***it. but eleven year olds have heard worse (probably). then theres online which you can chat with other people but you don't have to. Also this game can be scary for younger children. especially the witch. but thats about it.
