Come Out Fighting: Secret areas:  There are two secret areas in this level. The first is found at the first house where you have to exit your tank. Go to the barn door and jump at the wall to the left of it. You will go through the wall into a room with a giant chair and a very small door with a green light shining out. There are also two health packs in the room. The second secret area is at the second house. Go inside and clear out the house. In the back room on the right is a window where you can shoot the machine gunner that was shooting at you while you were coming into the house. Go back downstairs and outside. Jump over the sandbags and onto the barbed wire. Follow it to the house. You will go through the wall and down a hallway. At the end is a room with a Nazi UFO and four health packs.

Depot Saboteurs: Secret room:  On the second British level, Depot Saboteurs, in the area where you blow up all the fuel drums is a large brown church-looking building. Go up to the right-hand side door and throw two sticking grenades at it. Then, go up to it and press Action. Move back and throw one more grenade at the door to blow it up. Follow the stairs down to a room with a Bren, field pack, and some grenades.

First City To Fall: Easy completion:  First, go to the building on fire and get the health pack. Then, wait until the tanks kill everyone and blow up the building entrance. Go inside and get the two health packs. Kill the man with a rocket launcher. Go outside and stand in front of the M12. It will not go anywhere. Get to where you can snipe enemies with the M1 Garand and where they cannot see the M12. Go get the health pack by the city gates and pick up any left over from the battle. Around the corner is a room with a rocket launcher and a health pack. Down the street are more rocket launching Nazis. Stand in front of the M12 and snipe the Panzerschrecks again. Ease around the corner and there will be a building where about twenty five enemies will come out from. Set and snipe them. Go to the end of the street and into the building to kill two more anti-tank soldiers. Go in the basement and get a checkpoint. Then, go through the tunnels and get to the machine gun. Kill all the Nazis until the theater is blown up. Once they are all dead, go down another set of stairs and out the door. There are two Nazis with rocket launchers where the machine gun is located. Kill them and go down the sewers to complete the level.

The Flag Must Fall: MG42 machine gun:  Go out of the building that you started at. Go up the hill outside, then go into the trench on your left until you reach a hill. Turn right, clear out the pillbox, then get out of the pillbox and go straight. Clear out the next pillbox. Go back out of the trench and turn to the right. There will be another trench here. Do not go into it yet. Pass it, turn right, and go downhill into another trench. There should be a path leading left as you enter the trench. Follow it and you will find the MG42, which is a machine gun that you can carry that is just like the stationary guns that were shooting you earlier.

Charge the big bunker on the top of the hill before you clear out the other bunkers. Then, clear out some trenches and the bunker. Next, lower the Nazi flag and you are done.

Underground Passage: Creepy room:  On the "Underground Passage" level, the second American mission, go down the spiral stairs and go through the door on the right. Clear out that room of Nazis and the next one past it. Then, go back to the middle room and clear it out again. Go to the walkway that has a field pack and a door. Throw two grenades at the door then go up to it and press Action. Note: You will not see an "Action" icon, but it does not work unless that button is pressed. Then, throw one more grenade at the door. It helps to throw it at the wall next to it so that it lands at the base of the door. This will blow it open. Go down that passageway to find the "creepy" room that contains a ghost baby in a crib, floating candles, a giant rat, a teddy bear, a "sticky" bear (basically a sticky grenade that you get 99 of), a flushable toilet, a MG40, and a Browning .30.

Underground Passage: Dance party:  Near the end of the "Underground Passage" level, the second American mission, is a boarded-up tunnel. Throw some grenades at it to blow it open. At the end of that tunnel are some Nazis having a dance party. There is also a Browning .30 in the corner.

Underground Passage: Bulletproof Nazis:  In the second secret room, you cannot kill the Nazis with bullets. However, you can with grenades.
