Origins Map Layout Of Entire Level

well here it is the final map pack in the Call Of Duty Black Ops 2 Zombie levels and it is out of this world! Well its in the same world, earth only way back in time to the First World War which reveals how all this horrific holocaust has come about throughout all of the zombie levels.
So far I have found that there is a new powerup called "Zombie Blood" which makes the screen go dark red. Its very handy as a pickup as it is kind of like Vulture Aids green smoke that you see when you kill a zombie and then stand in it, the zombies will ignore you. Vulture Aid is from the Buried Zombie Map level in the previous map pack. The Zombie Blood pickup makes the zombies ignore you for a brief amount of time until it wears off, They will not hit you or chase after you while it is on.
Here is a screen shot of what it looks like to pickup and what your HUD looks like then you have it activated:
