A cyber-gothic role-playing game for mature players.
Waste
Rad Zone
This area is deep in the UnderHive and very old. Its tunnels & structures are unstable & feel warm o the touch. Those that spend more days that their Toughness here must test it or have radiation sickness. Deeper into the R-Zone sickness and later-life cancer is automatic. Nothing can live or grow here. Uranium is mined here though, and used in the ammo factory to make depleted-uranium bullets (which are excellent for armour penetration).
Sludge Pool
This has gathered around the base of the SlagHeap, at the bottom of the gutter shafts, trickling an pouring into a great water-fall through the corroded layers of SpireShell and forming into rivers and streams across the lowest level. It allows the scavvies that live there to make tox-bombs and poisons. Otherwise it is useless and dangerous, giving off burning fumes. A slow, flammable build-up of this gas is occuring in parts of the lowest level where it is getting trapped. If the shell had not been compromised, this would not have happened. Heavy weapons or flamer fire in these areas will cause dangerous explosions. (suggestion: 1d6 str 6 hits with 1d3" blast template on first shot).

Slag Heap
The SlagHeap is an increasing danger having eaten throgh the Shell over the years. It is encroaching upon the scavvie Spook cache and may destroy it if it collapses into the chamber the Spook is found in. Occasionally the Slag can be re-used by the scavvies (one day, when its composition has changed it will be mined). When an Ash-Storm hits the Spire, ash will billow through the gap and fill this lower level.
These resources above are all scavvy controlled.
Chem Pits
Chemical waste from old factories in the UnderHive was once poured into even old Cooling Towers below them. These cooling towers eventualy filled up and were sealed over and then used as supports for part of the upper level. After centuries the chemical composition had changed and unearthed. The chemicals here are now of some value and factories were built around the tops of the old cooling towers. The chemicals are used to make fuel, solvents, drugs, weapons and countless other things. These chemicals are integral to the working and living of the Spire. If they were ever lost or used up, chemicals would have to be imported from another spire at more expense.
UnderHive gangs racket the Chem-Pits, much to the annoyance of the Tech-gangs that are using them in their various industries. They are a regular site of fighting between gangs trying to take the racket from another, and techs trying to beat the gangs off. Occasionally scavvies make raids on the chem-pits. The scavvies are planning to collect toxic chemicals to spread into the air vents of the UpperHive.
