Shell

Shells are round, blue spheres fired by land vehicles in Civilization Stage that explode when they hit their target, causing damage. They also leave a blue trail through the air, like those left by torpedoes.

Unlike their Earth counterparts, shells used in the Spore Galaxy behave like torpedoes, although it seems that they are initially fired out of a gun instead of making use of their own propulsion. They seem to be more like primitive ancestors of the torpedo, even though torpedo-firing sea vehicles are usually developed only a short time later.

After being fired, they usually reach a maximum height and then fall down towards their target - usually a stationary target such as a building or turret. However, if the target is moving - for example, a vehicle - the shell will change direction and follow the target until it hits. They can follow fast-moving vehicles for hundreds of metres. Shells are even apparently capable of climbing beyond their usual maximum height when hunting flying epic creatures.

Shells are only used in Civilization Stage, and as mentioned earlier, they are later replaced by the torpedo technology previously used only by sea vehicles.
