Map

Every map consists of a certain number of spaces that are placed together in a grid. Spaces are adjacent when they are horizontally or vertically adjacent. A space's surroundings are the eight spaces that surround it horizontally, vertically or diagonally. Every space contains a tile, up to one ground unit and up to one air unit. At any given time during the action phase, one unit can be the active unit; this unit can occupy a third unit slot on some space. Every space has a number of humidity counters and possibly also Chaos counters, stacks of Gas, a Snow marker, a Frostbite marker, a Firestorm marker, a Bonedrought marker and a Death marker.

Vision

Each player can only see the contents of spaces that are close to their own tiles and units; a space is within a player's vision if the squared Euclidean distance between it and any tile or unit owned by that player is less than or equal to the vision radius of that tile or unit.

Ranges

Note that all ability ranges and vision radii are expressed in squared Euclidean distance, not in Euclidean distance.

Movement Speed

Because units only move orthogonally, movement speeds are expressed in Manhattan distance.
