All of Zone Mortalis Missions detailed within this Journal Tactica assume that there is a ceiling over the Battlefield. This affects the Rules by preventing the use of indirect fire weapons and aircraft but also in conjunction with the Rules for Walls, divides the Battlefield into discrete areas. It is usually impractical to represent the ceiling with Terrain, but it is good practice for both Players to confirm prior to selecting Armies for, and playing any of the Zone Mortalis Missions, that they understand how the ceiling impacts gameplay.
