The battlesphere is where combat takes place, and consists of a two dimensional map of fixed width and height. So its not really a sphere! The map is made of terrain hexes.
There are four types of terrain within the sphere:
|Chaos sea is impenetrable, no titan can move over it and it is therefore a very important strategic feature. Try not to let yourself get trapped between mountains and the sea as the opposition can pummel you while you slowly crawl away.|
|Lowland, beautifully flat and featureless. It costs only a single move point to cross.|
Highland, with rolling hills and valleys.
Mountains, rugged and broken towers of rock and sharp cliffs make travel very slow.
Each hex may have bio-mass growing upon it. This is the unnatural growth that spreads swiftly upon the battlesphere, which is what your Titans harvest and use to reproduce. Bio-mass will grow out from a central point, so grabbing bio-mass fields and harvesting them dry is very important. A hex can hold at most 7 units of bio-mass, and a Titan can harvest 1 unit per go.
When a titan dies they will decompose and contribute a quarter of their mass back into the hex.
The more advanced Titans will not be able to harvest the basic bio-mass shown above. When this happens (you will know!) you must start to move your clan to the South or East, for this is where the next realm of bio-mass grows.
The border for different bio-mass consumption are:
Tech 0-15= green bio-mass
Tech 16= orange bio-mass
Tech 51= Purple bio-mass
Tech 151= Blue bio-mass
