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

    @XBlueBeam Are you saying this took inspiration from mine or that i should take inspiration from this? Either way, i've seen your fusion drive before, and i learned how to make nano-scale gas generators from it.

    only works with H-isp disabled! it feeds of the DSTW reaction mass line

    added a sort of water sprinkler system to slowly cool the crmc shield on the AFT in case it gets too hot
