I wonder how to remove contaminated areas!


If a contaminated area exists, you should concentrate on removing it.

This is because if the contaminated area remains, regardless of the mission type, the mission can not be completed.

If you kill a zombie or deploy a soldier from a cube with a contaminated area and close that cube, the contaminated area will remove.



Cubes that do not have contaminated areas should be avoided as much as possible to complete the mission.
