Prisoner of War Cheats

Free hints
Gain a load of currency and then save the game. Afterwards, talk to the Major which gives you hints. You should get 150 currency to get all three hints. After you have heard these helpful hints, load from the last save point and use the info to help you on your objective. If you keep the same amount of currency, you can do this for the next objective. As you have used the hints but not saved afterwards, at the end of the level the game will not register their use, and you can get a higher grade at the end.

No capture or shooting
Note: This will only work if you save regularly. If during an objective you are shot or captured, load from the last save point. If you save after every objective, you will not have to do those objectives again.

Lockpick in Colditz
The lockpick is on the desk at the start. Run and swipe the lockpick then run back to the barracks and open up your hiding place. Transfer the lockpick into it. It will then be there when you get back to it.

Hiding place in Colditz
During your second time in Colditz, when trying to grapple the balcony in objective 2 and a guard sees you, run into the closet hiding place in the main stairway. No guards will see you. This is also a good place to hide if you miss roll call.

Easy loot in Stalag Luft
Go into mess hall and ask the people you gave to bribe for help to distract the guards. He will start screaming on the floor. Wait until the guard approaches him. Then, go behind the kitchen and take the brass key located there and find lots of contraband. You can do this every day. As long as you are quick, you will not get caught even when the chef cries for the guards.
