some cool ideas for forge maps
-chain locker
Hazards: rotating kinetic tank sized horizontal pulleys, man sized chain links, crushing anchor falling hazard, huge vertically oriented rotating power transmission gears
Other thoughts: gantry, stacked cargo, vehicle elevators, small trapezoidal bulletproof glass security clearance corner guard rooms, periodic raising and lowering of the primary anchor
Shape: elliptical or rounded rectangular
-fission pit
*Hazards:* occasional gamma ray hud visual effects,
*Other thoughts:* control rods and zirconium bundles randomly raise up and down, multiple loud sizzling steam production sounds, hud effect emitters, exterior steam condensation of player visor
Shape: 
octagonal
-pool
*Hazards:* turbo pump fan blades, man sized ball valves, water pressure flushes players through ducts off the map
*Other thoughts:* centrifugal pumps fresh water in and gates flush sizzling water out, pool water surface height varies temporarily exposing routes players can traverse
*Shape:* rectangular like tokamak1 and better defined rooms and connecting tunnels. Perimeter of pool solid concrete surrounded by railings. Pool volume with staircase scaffolding that will not impede the draining and refilling of pool water surface level
-minuteman silo
*Hazards:* periodic launch exhaust blast,
Other thoughts: mechanized icbm reloader to replace launched missile, hydrazine storage, exotic propellant room, oxidizer room, observation deck, control room, bull horns, spinning flashing lights (yellow for giant mechanized arm and hose connection warning, orange for cryogenic pressurization warning, red for launch sequence)
Shape: vertically oriented cylindrical w/ medium side rooms and elaborate central scaffolding
-turbine
Hazards: base sized exposed turbofan blades, emp lightning, map sized magneto solenoid coil with rotating spatial hazard because of radial support brackets and exterior generator housing
Other thoughts: man sized steam pipe sounds, rain room (condenser room, subdued red lighting, suspended above a drain pit, rain fx, Dripping pipes in the dark vibe, shadowy staircase scaffolding with good verticality ), double Y bracket style heat exchangers/radiator surfaces
Shape: horizontally oriented cylinder with extensive elongated room compartmentalization, tight quarters at the ends of the cylinder, opens up visually in the middle of the cylinder with more freedom of movement
