Structures of the two factions, Arm and Core, in Total Annihilation.
Arm
Tier 1
Solar Collector
Type: Resource Generator
Built By: Commander, Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane.
Comments: Basic energy collector. Gives 20 Solar per tick.
Wind Generator
Type: Resource Generator
Built By: Commander, Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane.
Comments: Another basic energy collector. Best used on windy planets. The amount of energy produced depends on wind speed which varies from planet to planet and from time to time. Wind seems to have no affect on ballistic weapons.
Tidal Generator
Type: Resource Generator
Built By: Commander, Construction Ship, Construction Hovercraft, and Construction Seaplane.
Comments: Yet another basic energy generator, which varies in output with the tides. Often overlooked.
Energy Storage
Type: Resource Storage
Built By: Commander, Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane
Comments: Stores 3000 units of energy. Sometimes used to even out the ups-and-downs in Wind Generator power, or to ensure power is available for heavy artillery.
Metal Storage
Type: Resource Storage
Built By: Commander, Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane
Comments: Sometimes useful, if one reclaims a large amount of wrecks in battle. Otherwise it is rarely needed.
Metal Maker
Type: Resource Generator
Built By: Commander, Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane
Comments: Very useful, as it allows for the conversion of the more plentiful resource, energy, to be converted into something more coveted: metal. Converts 60 units of energy into one unit of metal.
Floating Metal maker
Type: Resource Generator
Built By: Commander, Construction Ship, Construction Hovercraft, Construction Seaplane
Comments: More expensive than a land Metal Maker, and it floats. Otherwise, it's just the same.
Underwater Energy Storage
Underwater Metal Storage
Underwater Metal Extractor
Tier 2
Geothermal PowerPlant
Type: Resource Generator
Built By: Tier 1 Construction Kbot, Tier 1 Construction Vehicle, Tier 1 Construction Aircraft, Construction Hovercraft, and Construction Seaplane.
Comments: This power plant can only be placed on top of venting cracks in the ground. They take time to build, but when completed, they will produce 250 energy per tick, which is a great bonus.
