Doom 3 is a fantastic FPS horror game developed by ID Software in 2004. This game shows a lot of positive role models, but, it runs with very mature content, such as bloody, gory, brutal violence, swearing, disturbing images, and sometimes jump-scares throughout the game. Doom 3 is also very dark, not as in tone, but in as you can't see a single thing in front of you, because there are a few scenes where the lights will go completely out. Enemies can be blown up, sawed/sliced, and shot into a big gory pile of organs as well. The game's storyline is where you play as a space marine on Mars, working for a research company called the UAC (Union Aerospace Corporation). Your job is to look for a missing scientist in Mars City Underground, witch is where you and the scientist realize that an outbreak of demons and evil souls have escaped from another dimension named Hell, killing everyone. After words, the scientist is turned into a zombie, attempting to kill you, and you need to shoot it. Also, there are parts in the game where swear words are used, such as Jack*ss, f*ck, and sh*t. But, to be honest, the biggest maturity of the game is the amount of gore that is featured, and one of the most brutal weapons to use in the game is the chainsaw. This weapon is capable of sawing through enemies within seconds, causing lungs, brains, liver, and intestines to fall on the ground with blood spraying (And yes, this IS shown on screen). Doom 3 is not for young children, but horror/gore fans will enjoy it very much.
