Dead Soldier: On the map "Kino Der Toten", you will start in a lobby area. Go up the stairs on the left side of the room and look left down the passage at the top; there is a boarded-up door there where zombies will come in. Now you will want to go away from this door and battle the zombies that come from the lower section. I actually believe that you have to open a door to the next section before this easter egg will appear, so just fight for a bit and open the next section when you can. After you have done this, return to the door that I mentioned before. You should see a dead body leaning against it from the other side. If you look closely you will see it's not a zombie corpse but a mauled soldier that was trying to escape but didn't make it. It's a bit creepy!

"Random Weapon Box" Locator: Some of you who are observant should already know this one, but I thought I'd put it here for any who don't. Once you turn on the power there will be a crate on the map that will give you a random weapon for under a 1000 points. This crate is the key to getting more advanced weapons and is pretty important to your continued survival in higher rounds. The trick is, it's location is random too, and there is something like 9 different places on the map it can be! Looking manually around the map can be not only a bother, but dangerous too. To find the position of the box look carefully on the walls around rooms for a layout drawing of the whole map area(at "Kino Der Toten" there is one at the back of the stage). The layout map should have a series of unlit light bulbs sticking out of it, these are the locations the RWB can be. One of the bulbs will be lit up(after you power on), it goes without saying that this is the place the box is. Hope this helps you find it!
