In this mission,you are at docks.Time for invasion,you'll have to sneak out to a switch and switch it,so the machine crosses you a bridge over the boat.Now when you're there,you must steal a item but be careful,those 4 soldiers may not look dangerous but believe me,they are.

If you think that the mission is not accessable then you're wrong,here are some hints :

The area is not fully placed with army dudes
The area is not fully blocked,use your mind to get to the point.
Once you're at the boat,watch closely where to step.

Another hint : the first part on the docks,the thing is that you can get passed without being noticed,but on boat you can't.

Another hint 2 : the switch might not be just "inside" storage houses.

If this mission is hard for you use "HESOYAM"
