There's a little area that you can climb into, there are some satchel charges and a medkit. Next you go to the big bunker the entrance is on the other side and there are two krauts in it. There's another one in a smaller bunker next to it. The artillery gun can not hurt you and does not affect the mission completion, but it's fun to blow it up just the same. Remember to move away a sufficient distance. There are two more exits, one into a minefield, the other into the open. When you get into the open you see a trench with a swarm of krauts in and around it. Take them out and go down the trench to the end. Next you exit the trench and go left.
There are a couple of areas you can get into on your left, they have ammo and stuff. Go to the end of the "corridor", there's a kraut and a medpack in a secret area on the left at the very end. backtrack to the point where to burning assault-gun/tank is. Go behind the bunker where the two krauts were. You will find an entrance down into a tunnel there. There's a kraut in the tunnel, when you kill him a grenade drops in the tunnel (don't ask me how but it does) run at it and pick it up. If you do not a section of tunnel will collapse. There are two rooms with a kraut in each. They both lead down a tunnel into more bunkers. There is a soldier and an officer in the bunker. After you kill them go up the stairs to the steel door and open it. (Press space bar)
There are two Germans at the left, blast them. You can get a medkit from behind a rock on the right. Back where you shot the two jerries there is another artillery bunker. There's two krauts in it. Now comes the tricky part, you must get through the ammo dump but if you don't do what I tell you you'll get bombed every time. First, throw a grenade at the boxes and duck in the bunker, when the explosions stop go back there, frag the kraut at the right and throw another grenade, run back. Now start to walk down where you threw the grenade, turn around and run back, the bombs will drop harmlessly on the open ground. Now walk down to the end of the path, be aware of the kraut on the left. Go around the bend and enter the bunker at the end. There will be two krauts on the left.
When you leave the bunker you will see railroad tracks. There will be a jerry plane trying to strafe you and two krauts behind a hedge. Your best be is to run for the trench that's past the tracks. Frome here you can take out the two krauts. There are two passages one on the left and one on the right. You can go either way because they lead to the same open area. There are a total of about ten krauts there and trucks and boxes and stuff for you to take cover behind. When you take them all out go into the tunnel. There is a kraut in the tunnel. After you're done with him continue down the tunnel. On the second right turn there's a kraut in the smoke. Next you turn left and run through the flame. See the radio box, that means you just finished the level Atlantic Wall.
