Hitpoints

Each unit, building and terrain figure has a set number of hitpoints. When a figure reaches 0 hitpoints, it dies. Hitpoints are not to be confused with number of figures - each individual figure of a unit of building has their own hit points. So a fully u[graded city has 5 figures with 3 hitpoints each.

Mechanics
Most often, damage is dealt through combat, be it gunfire or explosives. When a figure survives combat, it immediately regenerates all its hitpoints. The same holds for surviving weather effects or gas. Hitpoints can be temporarily decreased by gas or bonedrought, and by combat. When a unit or building loses all figures, it is gone from the map.
