I picked a good spot to enjoy the spectacular scene of detonating the lighthouse.

Then the enemy's alarm went off.
Here it was time to start collecting MP40 bullets. Continue up to the top of the hill and after sparing the enemy troop carrier enter the second floor castle along the rotten wall on the left hand side. After passing through a section of the wall passage enter from the left hand side and destroy 5 radio transmitters. Then come out and go down the square of the castle from the right side destroy the enemy and enter the enemy fortification depot at the door on the right hand side. After a fierce battle to capture the foreground my superiors told me to get the documents and destroy the enemy fortifications.
