Great Escape, The Cheats

On the train level, after you have gone to the very end of the train and
got the pistol and the sub machine guns and after you have battled on
the top of the train you need to jump off the train in order to gain the
unlimited health and weapons once you have jumped in order to make this
cheat work you need to tap xxxx before you hit the ground

While you are driving the tank, you encounter another tank. You cannot fight; park somewhere safe and run into the house with the stairs. Go to one of the levers and pull it. You will see a train appear and hit the tank, clearing the path for you.

Once you have the key, go to the room before the first class section. Use the key to open the silver barred door to your right. You will get weapons. Then, get on top of the train by climbing the ladder. There will be guards on top of the train. Shoot everyone and go down every ladder, as you will get swarmed by guards on top. When you go down the ladder, they come to you and you can kill them all. Once they are all dead, you can run to where you hid Blythe. Go to the jump off point and run through the door.
