Call of Duty: World at War

First as you start you kill all the zombies untill you reach about $3000. Then you go to the room which says Help. Then go over to the mystery box to your left and wait until the question marks on top are at there peak of gold then open the box. You will then get a ray gun!

You can find this trophy by opening the door that has "Comm" on it in Shi No Numa. Then, open the door where the perk machine is located. There is a door on each side of the perk machine. Go in the one on the right. As soon as you enter that door, take a left. There is a black phone sitting on the table next to a radio. Go to the phone and hold [Reload]. You may need to do this two or three times. You will start to hear numbers being dialed, it will start to ring, and the trophy will be unlocked.

You can complete this task by killing all but one zombie before they tear down the window boards. Let the last zombie live, and while he is tearing down the window boards, immediately repair them. Although you will not get points for repairing the boards, you will get the trophy. It is funny to watch the zombie get frustrated when it makes no progress, but do not get too close - it will reach through and take a swing at you.

Complete the following tasks to unlock PlayStation 3 Trophies.

Find some dead bodies. Run up to them and make sure no one else is around besides your teammates. Get down into laying position. Then crawl into what appears to be the body of the dead person, so it looks like there are fragments of the body around your HUD. Lower your gun, but have it high enough to still see what is coming. This trick will make it harder for people to see you unless they are paying close attention to the ground. The flaws to this trick is that people can sneak up from behind and see you, and you can only see in one direction without moving. After a few kills move to another location because other players will pick up on your trick and grenade or rush you.

Play in Co-op mode. By the window at the back that you can see a truck out of, find a corner that is to the right of that window. Have one player go there and crouch down. Have the other player jump on top of him. Then have the player at the bottom stand up. You will now be inside of each other and are invincible as long as you do not move. If a zombie comes in, knife him. Shooting will not always work.
