Medal of Honor: Frontline Cheats

There is a Nazi soldier practicing a speech in a hall where you find
the map behind the painting. Instead of going around on the top, go
downstairs and run up to him. He will automatically fall back and die
without a single shot. The only downside is that you cannot get a gold
star for this mission if this is done.
Hint:On Track:UFO:
When you get outside to Sturmgeist's train, look
up and to the right. You will see a UFO flying in the air. If you look
closely, it has the Nazi symbol, and colors on it.
