**Level Variables** (94 bytes)

    0000  int16       Data Length. = 94
    0002  byte        Mist; Unused (0x00)
    0003  byte        Gravity; Unused (0x00)
    0004  byte        Radiation poisoning level, in 0.5 LBP
    0005  byte        Gravity, in 25% OR bio contamination level, in 0.5 LBP
    0006  byte        Gravity switch. If 0, ```0005``` is bio contamination. Gravity mod otherwise.
    0007  byte        Bio contamination register. Must be >1 to have contamination to register
    0008  byte        Radiation register. Must be >1 to have radiation to register
    0009  uint32      Exit Time; Unused in savegame
    000D  [3*27]byte  3 Automap Variables entries, for first, second, full-screen (see below)


> Hazards are notified from value 0x01, but affect only starting from value 0x02 (1 LBP).
