Gears of War 3 is an excellent but very gory third-person shooter game. The player plays as Marcus Fenix, a man in search of his lost father, and other COGS, people who fight evil alien races known as the Locust and the Lambent.
Violence 10/10: Players will use shotguns, pistols, sniper rifles, mortars, machine guns and swords to kill thousands of alien, and in some modes, human enemies. Blood will visibly be shown when enemies are shot, and blood will begin to stain the walls and floor if the player is shot too many times. Stronger weapons may cause dismemberment if used at close range. Players also have the ability to perform a finishing move when enemies are injured, which may include tearing off limbs, decapitation, torching somebody's insides or crushing skulls. All of this is shown is realistic and graphic detail, but fortunately, this can be filtered out in the options menu.
Language 8/10: Players will hear frequent and sometimes strong language within the game, including f--k, mother f--ker, sh-t, a-shole, a-s, b-tch, h-ll, d-mn, and crap. Like the violence, strong language can be filtered out (I must note that only stronger words like f-ck, sh-t, and b-tch will be filtered, but in rare occasions, one of those words may be slipped.) God's name is used in vain quite a bit. One female character says to a male character that she's going to "raise his voice an octave," which would be considered inappropriate in my family.
Sexual content 2/10: Very little throughout the game. However, there is a scene where there is trading, in which women are included. Also, an alien character, who actually looks very humans, has a tight shirt, making her breasts rather noticable. However, it is not portrayed in a sexual way.
Drugs/alcohol/smoking 1/10: One reference to "beer," but nothing more.
Overall, an excellent game that I would recommend for ages 15+, due to extreme amounts of blood and gore, and frequent and strong language. If you are going to use the filters, I would recommend it for ages 13+.
