Normandy 1 "Lighthouse" Easter Egg.This works in the Campaign/Single Player modes. There are 10 blue bottles scattered around the level, it takes some time to find them all and the result is not particularly impressive, in fact it is hardly worth doing, maybe if you are very bored!!
Bottles can be found in the following locations, make sure No.10 is the last one you smash. 1: In the lower level, two guards talking by a room with a desk inside, bottle is on floor by the desk.
2: In the room with the explosive bags, smash the wooden cupboard doors to find it.
3: In the sleeping quarters, under a bunk bed.
4: In the sleeping quarters, top of metal locker.
5: On the shelf above desk through double doors marked "Gesch B".
6: In the dining room on a table.
7: In the kitchen area, lying in an open cupboard.
8: In the room marked by a red sign "Arzt", top of metal locker.Make these the last two. 9: Through metal gates under raised "Gesch D" sign, turn left & room on right, bottle on table.
10: In sleeping quarters next door to above room, smash last bottle & shoot drunk guard.
