NEREUS MK1 is a preheat-breeder cycle semi-destroyable fusion drive. It runs on only water, and can function in reactor-only mode. Water is used as fuel as well as reaction mass - exhaust is composed of superheated steam and fusion waste products.

    made SLTW the default fuel, fixed electrolysers breaking down (pressure), fixed lopsided plume (stray PUMP pixel), and added some QRTZ here and there for extra strength
