The letter said this. Written by Nikolai or someone else.

December 10th, 1917

It appears that my exile from my motherland may have be tortituous. I just recieved orders to ''undertake a vital mission in Northern France. ''(aka the Zombies map)

This can prove how why the robot was possibly there and why the map will take part in Northern France.
