A Vicious Cycle: Ambush
In the mission "A Vicious Cycle" (the last level of the fourth assignment), there is a secret area along the road. After you destroy the bridge with your demolition charges, go down the road until you see a long stone wall on the right. There is an opening in the hedgerow to allow you to get back there, or you can jump the wall. This is a perfect location to ambush the enemy.

I, Panzerknacker
The last level has two objectives: "Assemble Panzerknacker" and "Escape Castle". A Panzerknacker is a automaton (robot) that you face in the last level. First, go down the stairs and through the halls until you reach two large wooden tables. Press "Action" and the Panzerknacker will assemble -- he is red, and the enemy ones are blue. He has a SMG, and helps you, but you must cover him because he can die very easily. Next, proceed past the fire place and about four men will be there. Kill them. It takes the Panzerknacker awhile to search the areas. Go right and crawl. There is a secret location under the meat hanging from the wall that contains a health kit, ammo, and more. Return and you will eventually reach a entrance to a room with a exit straight ahead and to the right. Guards will appear from both directions, so be careful. You will end up going straight and reach some stairs. There is an enemy Panzerknacker above the stairs with a bazooka -- kill him quickly. You will see a vent to the right - do not enter it yet. Continue ahead, and turn left. There may be one guard behind the boxes. If not, take the health kit and ammo then return to the vent. Enter and Panzerknacker will disappear and reappear in the vent. This vent leads you to a room which leads to the courtyard of the castle -- you will remember this area, it is where you entered the castle 3 levels prior. There is a tank guarding the exit. Either kill it or not, then proceed straight and to the right, over the bridge, to escape.

Liberation: Street By Street: Easy kill
When you reach the bar with the three Nazis (one behind the bar and the other two in front having a drink), choose the petrol bombs and crouch. Sneak up to the bar about ten or fifteen feet away from the Nazis. Note: They will not see you unless you stand up or change weapons. Throw a petrol bomb at the bar. This will kill all three Nazis. Then, finish off the rest of them that appear from behind you, including the Nazi up in the balcony above the bar. Note: To kill the Nazi up in the balcony without getting hit, sneak under him and throw a petrol bomb at the bottom of the balcony.

Hunt For The Desert Fox: Hidden ammunition and health
In the first level, go down the stairs from your room. Face the door on the opposite wall between the two flights of stairs, then turn left. You will approach an opening in the wall leading to a small room. Inside is a pistol-armed Nazi. After you have disposed of him, jump on top of the nearest bench, then jump through the window and into the room. Inside, in the corner in front of the door, are a box of SMG rounds, pistol rounds, and a health kit. In the third level, you can get on top of the second fuel truck and then jump to the nearest ledge to find ammunition and health.

When you go into the other room in your second mission you will see red lockers near the suitcases. Shoot them to get ammunition for your machine gun,

Lighting The Torch: Hidden first aid kit
When you have just arrived at the supply depot in a stolen truck, jump out and turn to your right. Keep going until you see another truck. Kill the men that may exit it. Look around that area until you find a box sticking out of the wall that is slightly smaller than the others. Shoot it until it breaks, then go to where the box used to be. Squat down and face the wall. You should see a small crawl space. Go in to find a small area with one first aid kit.

Street By Street: Falling sniper
When you go to the building with the Moulin Rouge signs, up on the fourth floor is a sniper. Shoot him to see him fall to his death and smash through the Moulin Rouge roof, then onto the ground.

Wewlsburg: Dark Camelot: Field surgeon pack
In the Dark Camelot mission, second level, there is a hidden field surgeon pack in the fireplace. After you grab the knife, go down the hall and duck into the opening there. Once you are in the fireplace, go to the back of it and you will climb up the wall. At the top is a little alcove and inside is the field surgeon pack.

Wewelsburg: Dark Camelot: Valhalla hidden area
Play the Valhalla stage in the Wewelsburg: Dark Camelot level. When you reach near the end of the level, before you go to the right you will see a picture of a "red knight" riding a horse on the wall. Do not go down that way just yet. Instead, go to the area to the left of the picture. Once there, you will see three wall-lamps. Press "Action" to move the lamps, then turn the lamps in the following order: Middle, Left, Right. Then, turn to your right and a secret room will open. You will find one box of Rifle rounds, one box of crossbow rounds, one 44 stg assault rifle rounds, and two field surgeon packs inside the room.

Wewelsburg: Dark Camelot: Quicker crossbow
Press [Square] after shooting the crossbow to reload faster.

Wewelsburg: Dark Camelot: Alternate entrance to castle
Instead of going through the main gate, go through a gap in the wall just before the bridge. Go under the bridge and then straight on to the wall. You can then climb this, in the same way as a ladder.

Unlimited ammunition on uncompleted levels
Enable the "Unlimited ammunition" code, and complete the previous level to one that you have not played. After winning, save your game, and play that next level. You will not start with the cheat, but will have 999 rounds for your weapons and 99 grenades and bazooka rounds. Though the cheat is not enabled, you will never run out of ammunition.

Bonus ending sequence and extra medal
Successfully complete the game and receive all the medals and mementos. You will be able to view the special bonus FMV sequence. Depending on how well you completed the game (your evaluation), you will receive one of three medals. The best is the Legion Of Honor. If you receive this medial, you will also unlock a special bonus level.

Flushing out hiding enemies
Whenever an enemy is taking cover and about to shoot you, throw a Stick Grenade past them then shoot them when they go to kick it. For example, in Mission 1, Level 3, when you take the second gun and Nazis show up, all you need to do is throw a grenade at them to flush out the Erwins.

Killing enemies with objects
There are objects in several levels that you can shoot and will fall and kill enemies (or you). In Finding Valhalla, there is a deer's head mounted on the wall after you exit the tunnel in the fireplace. In the first level of the Wewelsburg mission, there is a crate hanging on a rope outside the building with the crowbar. Shoot the rope and the crate falls. In the first level of the Desert Fox mission, shoot the chandelier and it will fall and kill two enemies immediately. Finally, there are many such objects in the Crete level inside the archeological dig. They are little pan-like objects hanging from the ceiling. Shoot them and they fall and make small explosions.

Killing enemies in disguise mode
Get very close to the enemy and he will ask for your pass or papers. Give it to him then hold [R2]. He will pose for the picture. While keeping [R2] held, press [Circle] to draw your pistol. Fire immediately and the man should die.

Killing knights
The knights in armor encountered in certain levels can be easily killed by shooting them in the feet.

When on any level with knights, use your crossbow and aim at their helmet. Fire and it will kill them automatically. Then, press [Square] to reload faster.

Dealing with tanks
Tanks patrol certain areas you come across. They cannot be destroyed with automatic weapons such as submachine guns and pistols. Each area has a mounted machine gun. Be very selective about your weapon inventory. Each tank is very tough and armored. Do not try throwing petrol bombs at it. If you are at the front, strafe to avoid the explosive shells. Once the tanks turret has located you, moving and the shell will explode on the surface or a wall instead of you. The front firing machine gun is what you have to worry about. If you strafe, it can still hit you with its bullets. Try killing any enemies that are nearby then deal with the back of the tank. This will make you immune to the machine gun on the front. The weapons that the tank fears most the Anti-Tank Panzerfaust and Grenades. Make sure you not close to a wall before you fire the shell or you could go flying against a hard surface.

You can jump on top of tanks if you are in the correct position, usually from the back. This works well if you are invincible. If you are not, make sure that all nearby enemies are dead while you are attempting this. If you are not invincible, shoot the tank until it explodes. If you are invincible, you can throw petrol bombs directly on the top of the tank to destroy it.

Medieval warfare
Enable the "Civil War mode" code and go to any level with enemy knights.

Glitch: Jump through walls in Catacombs
In the Catacombs where you find the forged papers, you can jump through the brick walls if you are lined up correctly.

Glitch: Fly in Ally In The Desert
In the last mission, Ally in the Desert, Jimmy Paterson lands an airplane to airlift you off the base. Do not go to the plane or down the runway. Instead, run up to the plane's propeller and jump into it, going with the spinning blades. If done correctly, you will be flung across the landing strip and outside the game area. You will most likely have to try it several times before you are successful. Note: You can still complete the level by going to the plane. If you move around in mid-air, you eventually land at the back of the control tower. Use the D-Pad to get to the plane, but do not use the strafe buttons.

Glitch: Fall through bridge in Wewelsburg: A Vicious Cycle
When you get to the bridge that you have to destroy with the demolition charges, crouch and move forward on the bridge. You will fall through almost as if there was a hole in the bridge. However, if you run over the bridge you will not fall through.

Glitch: Instant replay in Street By Street
When you have neutralized the first of three heavy machine gun barricades, move forward down the road and turn left into the alley, killing two Nazis. After you have picked up the ammunition and field surgeon pack, backtrack out of the alley and kill the Nazi up in the balcony. Then, go back to the machine gun barricade. There should be a man behind the machine gun, a man up in the balcony (who should drop you another first aid kit ), and another one of your resistance fighters who will (if you kill him) drop you some petrol bombs.
