Phase changes have been added to the game system and most gases now have an associated Liquid and a pure solid phase.

The following exist only in solid state and have no gaseous form: Charcoal, Coal, Silicon, Iron, Copper, Nickel, Silver, Gold, Lead, Uranium.

Mixtures[edit]

Fuel 67% H2, 33% O2 Orange Autoignition at 573.15 K / 300 °C
HydroNox 50% H2, 50% N2O N/A Autoignition at 323.15 K / 50 °C
Air 75% N2, 25% O2 White 16 kPa Partial Pressure O2 minimum is required for human player breathing. Hyperoxia is not simulated.(NOTE: Suit air mixture should be 100% O2)
