Our Approach
Supersymmetry / Position
Supersymmetry is a Minecraft 1.12.2 tech modpack built on GT:CEu that treats real chemistry and physics as core gameplay mechanics. Every recipe follows stoichiometric ratios. Every machine line mirrors a real unit operation. Every voltage tier is gated by material properties — melting points, work-hardening, critical temperatures — that must be engineered before the tier can be reached. Physical chemistry knowledge directly translates into factory optimisation and faster tier advancement.
Design Axioms
1. STEM as mission
Accuracy is maintained by a team that includes working scientists and engineers. The project lead is a physicist at CERN. The objective is to ground players in real chemistry, physics, and engineering so that some are motivated to enter STEM fields and contribute to the sciences.

2. Stoichiometric accuracy
Recipes use real molar ratios. Balancing chemical equations by inspection is a practical skill for predicting throughput and detecting bottlenecks before building.

3. Unit operations as mechanics
Industrial chemical engineering unit operations are first-class gameplay systems. Distillation, electrolysis, catalytic cracking, polymerisation, cryogenic separation, and fluidized-bed reaction each have dedicated machine lines with real temperature and pressure constraints. Over 40 distinct unit operations are implemented across 150+ mods.

4. Material properties gate progression
Voltage tiers reflect real material limits. Copper oxidises above 400 K; aluminium work-hardens and needs cryogenic milling; titanium survives oxidising acids; tungsten melts at 3695 K; niobium-titanium superconducts only below 10 K. Every higher-tier cable, casing, and catalyst demands the process chain that produces a material capable of surviving that environment.

5. Nuclear engineering
Fission and fusion chains model isotope decay paths, neutron economy, breeding ratios, and coolant thermodynamics. Decay heat and void coefficient are design parameters that determine reactor safety margins.

Fluid & Gas Logistics
Oil & gas pipeline networks, cryogenic LNG terminals
Pipe networks support temperature, pressure, and phase-change dynamics. Cryogenic liquefaction, supercritical fluid transport, and vacuum distillation depend on correct pipe material and insulation selection.

Structural & Multiblock Engineering
Industrial plant layout, pressure vessel design
High-tier machines are built from casings, hatches, and busses in fixed 3-D patterns. Layout validation is strict: wrong-tier casings or missing maintenance hatches prevent formation. Some structures require external scaffolding or environmental shielding.

Environmental Hazards & Defence

Radiation zones, parasitic infestation, and faction-based raids pressure players to automate remote resource extraction and harden infrastructure. Base defence is a logistical constraint on factory placement and supply-line routing.

Rail & Orbital Logistics
Bulk freight rail, space launch systems
Bulk long-distance transport uses rail networks and, later, orbital launch and space-based resource extraction. Surface-based conveyor spam is deliberately inefficient at inter-biome scale.

Computation & Automation
DCS/SCADA, programmable logic controllers
Programmable controllers, sensor networks, and distributed logic enable closed-loop process control. A well-designed refinery self-regulates feedstock ratios, purges off-spec product, and signals maintenance needs without player intervention.

Progression Topology
The arc runs from primitive steam engines through nuclear reactors and theoretical physics to Overworld resource conquest, permanent space presence, solar system exploration, and interstellar travel. The endgame target is Kardashev type III scale. Quests mark conceptual thresholds while factory layout, piping, and automation logic remain entirely player-directed.
