Sniper Elite 4

There is a train car located in a building the eastern part of the map at the end of the train tracks. In this train car is the information Alsos needs to confirm that the Nazis are developing atomic weapon technology.

You can complete the primary objective, ‘Find the package for Alsos’, one of two ways; you can blow the train door off with a satchel charge (which will not get you this achievement) or search the harbor area for two officers, each carrying a key required to open the train car.

The first officer is located in the central/western part of the map inside a large building with train tracks. The second officer is located just south of the first in the wooded area of the map walking around a building with a tower next to it. Kill each officer and loot the bodies to find the keys.

Note: Remember, if enemies have been alerted to your position, it is possible that the officers will have moved from their patrolling locations.

Once you’ve retrieved both keys, head to the eastern part of the map to the large question mark labeled ‘Locate Package’. As you near the location, the question mark will change to a star labeled ‘Access Train’. Inside the building there are a good deal of enemies, so clear them out first before attempting to unlock the door. Once it’s safe, walk up to the train door and hold to open it. Inside the car is a briefcase. Picking it up will unlock the achievement.

It is recommended that you complete this on a lower difficulty.
