Thousands of standard years of industrial output has reduced the surface of Armageddon to barren wastelands and polluted oceans; humans can only survive within the artificial environment of the world's hive cities (the massive arcology-like structures that stand several kilometres tall) and Imperial military facilities. Food must be imported from off-planet, and clean air and water are precious commodities. Due to the inhospitable environmental conditions that exist outside of the planet's hive cities, almost all regiments of the Imperial Guard's Armageddon Steel Legion are trained as mechanised infantry who operate from the relative safety of their vehicles.
There are three main landmasses on Armageddon. Most human life is located on the main continent, which is split into two parts, Armageddon Prime and Armageddon Secundus, separated by the thick band of jungle known simply as the Equatorial Jungle. They each had their roles in the Wars for Armageddon but the majority of the fighting took place on the main continent. Most of the information presented here on Armageddon's geography will be limited to that provided by the areas given over to the fighting during the Third War for Armageddon. The bulk of the sub-continents of Armageddon Prime and Secundus are covered in ash wastes, the aftereffects of many millennia of industrial pollution. Several hive cities house the planet's human population and the industry of Armageddon; these include Tempestora, Death Mire and Volcanus on Armageddon Prime and Infernus, Hades, Acheron, Helsreach and Tartarus on Armageddon Secundus.
To the north of Armageddon Prime and Secondus are the Fire Wastes, which are home to the mining and resource gathering industries that support the hive cities' factories. This is an extremely arid region, which has been strip-mined far beyond the point that it can maintain any living ecosystem.
To the south of the main continent lies the ice-covered Deadlands. The polluted ice here is melted and heavily purified to provide a source of drinking water to the inhabitants of the Armageddon hive cities.
The Fire WastesEdit
The Fire Wastes are located in the far north of Armageddon, where one would expect a cold region of the polar north, possibly indicating that it is not in fact the furthest northerly region on the planet and perhaps it is a region that crosses the equator of the world instead. Regardless of its position, it is the location of many of the ore mines that supply the main settled Armageddon regions with resources in order to create the industry and weapons the world needs to survive.
Another river is the Serestus River which goes around the Black Lung Tar Pits and past the Serestus River Refinery and the Serestus River Mineral Storage Facility and exits into the Boiling Sea via the B'taani Bay Penal Colony.
The Black Lung Tar Pits are another region of inhospitable terrain, although these pits have been mined for thousands of years and the ore is used in the industrial processes of the main Armageddon continent.
The sea itself also contains the Aderbein Oil Platform, vital for the functioning of the weapons manufacturers on the mainland. The main port is named the Fire Harbour and is home to hundreds of miles of docks and rigging equipment, designed to transport the minerals excavated and refined in the Fire Wastes to Armageddon.
There is also another ore mine off of the main Fire Wastes map area, far to the east. There used to be an undersea pipeline just off of the map to the west, but that has since been destroyed when the other end of the pipeline was captured by the Orks.
The small frozen continent called the Deadlands is split into two areas, the Deadlands proper and the Netheria Peninsula. The entire continent is far enough to the south that it is completely covered by ice and as such is used primarily as a water creation and purification site. It was attacked with unexpectedly heavy forces by the Orks.
The Deadlands are the westernmost of the two regions on the continent. It contains one of the two main water processing plants, and this is broken down into the St. Capilene Water Processing Plant and the minor Phaedra River Water Processing Plant. The water is then pumped through overland pipes to the Lemaire Channel Water Pumping Station which stores and then pumps water through the undersea pipes to both Hive Helsreach and Hive Tartarus. There is also the Dante's Canyon Oil Drilling Station which supplies oil to the south of main Armageddon continent. The Valdez Gamma Oil Platform also provides oil and is located off the north east coast of the Deadlands. Another oil producing site is the Yarrick Point Oil Drilling Station, located far to the west. Finally, there is the Zebra Ice Station Defense Fortress which protects the entire region from orbital attacks and provides a vital bastion of strength to the defenders of the region.
There are two Ork Rok landing sites as well as an Ork submersible shipyard located to the north. These produce the huge Gigatankers that the Orks used to assault the hive cities on the south coast of Armageddon's main continent.
