The object of this map is to find the best route to kill the Boss. The routing is not obvious. As a general rule: If you run out of ammo you lost.

You have three possible endings.

1 - Find the yellow key and grap a ride with the helicopter.

2 - Find the red key, unlock the office and push the switch ...

3 - Fight through the map, collect sufficient ammo and kill the Boss. Even so he is in his cage the area is deadly.

General hints:

* Look for "Ammonution" compartments for critical supply of ammo for the stronger enemies.

* You need the yellow, blue, and red keys to access weapons. Without them you are with pistol and shot gun only. However the Devestator is located in well hidden secret locations. :D

* The subway (U-Bahn) works. After you entered the "SS Halle" you can enter the subway by foot. So no need to do DNCLIP.

* The upper level of the "Heizer" contains the screen showing the location of all secrets. Not quite spoiler but close. 

Key hints:

* Location of keys are identified with colored screens pointing to either the location of the key and/or switch to be activated.

* The yellow card screen is in the "Gestapo" room, the blue is near the Drinking Fountain and the red in the "Getriebe Haus".

Combination hint :

* The code for "Schalter 5001" can be found between the shower room and the Gestapo room in two separate locations.
