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, as well as various kinds of weather markers and counters. At any given time, one unit can be the active unit; this unit can occupy a third unit slot on some space.

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.
