|Easy Completion In Tractor Factory|
When you get up to the sniping area, crouch down in the window. There will be some ammunition and health in the corner if needed. Get it if desired, then snipe the first wave of soldiers with normal guns. When your "comrades" say that there are Panzershrecks, concentrate all of your fire there. Do not worry about the regular soldiers because they cannot aim well. Shoot the Panzershrecks until you see a man running up the road with a heavy machine gun. Shoot him then go to the left window and continue.

|Giant Apple In Operation Saturn|
Start the mission. Back up slightly and turn to your left. Find the tree near the road with no leaves (just branches). Face that tree, then drive up the right side of it, going off the road that you were on. Turn left and follow the dirt path in the snow that leads away from the mountain. After the path turns, look in the distance to find a strange object. Drive towards it to reach a giant hollow apple, with a UFO inside.
|Go Outside Level In The Square|
On the multi-player map The Square, go towards the building with no equipment in front of it. On the left side there is a wall. Jump onto the wall then jump onto the dirt. Next, jump down on the other side and you are now out of The Square. Other players cannot see you, but you can see them.
On the first tank level in the Russian campaign, it is best to use first person view to shoot the Nazis that have Panzershrecks and MP-40s. The MP-40s cannot hurt you, but are annoying. If you use third person view, you will usually miss.
|Teddy Bear In Surrender At Aachen|
In Surrender At Aachen (the third mission in the American campaign), go through the door and kill the four Nazis (grenades are useful). Go to the area straight from the door that you came through. There will be a MP-40 and a teddy bear here. Pick up the teddy bear and you will receive health and a message stating "The Bear is adorable".
