The Great Escape Cheats
The Greatest Escape mode
After finishing the game you will unlock the THE GREATEST ESCAPE option. This allows any level to be played with a time limit.
How to beat the tank
When 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.
Upon getting caught up on an objective push Select. This brings up your notebook, and tells you exactly where to go and what to do. It is not cheating but a feature built into the game.
Saving the game
While playing the missions, you will only be able to save a certain number of times. The amount of saves you get depends on the mission. Make sure to only save after you clear a major obstacle or objective.
