RAID: World War II

This Achievement is difficult but for the reasons written below:

-The game crashes often
-The game often gets buggy
-The unpredictability of the number of enemies and the positions of the objectives

These are the best tips I can give to anyone who wants to do it on Solo:

-Know the map, and the possible locations of the targets
-Kill everyone with the knife
-The field of view of the enemies is very limited, use this to your advantage
-The corpses set off the alarm, hide them if you kill someone
-Outside the tower it is almost useless to kill the guards, sneaking up to the tower
-Inside the tower it is recommended to kill everyone up to the third floor
-The fourth floor guards are impossible to kill given their location, ignore them
-The guards on the outer roof can be killed and thrown off the tower
-Advance patiently and kill someone only when you are sure that no other guard can see you, although this advice sometimes killing an isolated guard can trigger the alarm this is a problem of the game, there is no solution
-If you find some isolated guards that don't move, you can kill them by going against them pretty fast, even this advice doesn't always work due to the game's problems
-After placing the dynamite and pulling the lever, you have about 60 seconds to descend from the tower, if you have killed everyone, go the opposite way without creating fuss
-The Achievement unlocks as soon as you exit the tower
