In Doom 3 you don't just shoot demons , you go and talk to people and find PDA's. The PDA's give you info and let you statagize and check inventory. You also go throw finding keys and health. As you go throw the game you unlock lockers, and to get the code for the lockers you pick up other PDA's and go throw them. The game will scare you the first time you play. but as you get used to the suprises you don't gat as scared as the first time. When you beat the game you will feel good that you stoped the demons from taking over the arc. When you get to a dark spot you will be able to switch from your weapon to your flashlight. When you finale beat the game Doom Resurrection of evil will start years later. What I'm trying to say is if you like a good scare and fighting demons go get Doom 3 where they sell Xbox games.
