Weird Dance Party
Head to the second level of the Western Theater (the stage is entitled 'Underground Passage').

At the very end of the level, you will approach a hole in the brick wall (after killing the final two or three Nazis) that will be the obvious exit out of the tunnels. Don't go through the exit. Rather, walk backwards (retreat) past the last alcove, to the second from the last alcove on the left. Look carefully. You'll notice that this is a boarded-up side tunnel.

It takes about four (or more) grenades to explode the opening. Grenades are apparently the only thing that will destroy the 4 or 5 planks loosely covering the opening.

Once open, head down the tunnel. It's just a few feet and a couple of turns to the dance party. Incidently, there are 7 characters dancing around. 5 Germans, 1 Brit and 1 Russian (Tatiana).

Also, you can interact with the phonographs if you move behind the table. You'll see a radio(?) symbol appear (in the same way the symbol for moving your comrades appears). When you press 'x' you'll hear a record scratch sound (not terribly impressive).

There is also a M1919A6 machine gun that you can pick up in the room. Stay awhile, watch'm strut their stuff. The Russian woman takes the cake with some wacky break dance moves (there's even cardboard on the floor).

Sultan's room
This room is located in the second British level. At the end, after you have blown up the fuel depot, There will be two old looking buildings by the mountain-dead end. The one at the left that looks like a church or 3 loafs of bread put together. The door on the right has the Sultan's room. Don't go to the smaller building to the right. Throw 2 sticky grenades on the door, then examine it. After that, throw 2 more sticky grenades on it, and whatch it explode to reveal a hidden stair case. Go down it to find an Arabic guy playing an old guitar thing. You can get a health pack here also.

Hidden Child Room
In the level where you enter the undergound tunnels to blow up the ladders, start by going down the spiral staircase to dispose of the germans. Then enter the room to the right. There is a small alcove on the right side of this room. Throw a couple of grenades into the alcove, then examine the door and throw one more grenade into it. The explosion Will reveal this VERY CREEPY room.

Big Red Apple
In the Russian campaign, right at the beginning of the mission Operation Little Saturn, turn left and find a scraggly tree all by itself along the embankment. Go over/through the embankment just right of the tree, and then turn left and find a road that leads away from the rest of the board. After a while you will see a huge red apple in the distance. You can drive right through it to find something else that doesn't belong in a WWII game.

Teddy Bear
In the stage Surrender at Aachen (Western Front), you will be in an enemy occupied house right from the start. The small room directly across from where you start from has a small teddy bear you may acquire with that will restore your health.

Exceed Normal Ammo Maximum
Normally, all guns carry a nominal maximum of reserve bullets (i.e., MP40 carries 32 in the magazine and 160 rounds in reserve). You can exceed this maxima for your non-default guns by dying and restarting from a checkpoint.

The game will assume that you still carry the gun you previously had (i.e., MP40 in this example) and allow you to collect ammo for it even though you do not have the gun in your possession.

When you do choose to pick up the gun you've had on your previous play, you will find that you'll have more than the normal amount of ammo for that weapon.
