You cant.

yea, u basically hav to play through konquest, which could take sum time, but there r a few unlockable in the krypt, i think noob smoke is in there sumwere for like 4000 onyx koins

ok but wherei found onyx Koins without konquest b/c i am playing MKdeception Arcade on Ps2 i hopr u understand my meaning

u usually can get onxy koins in puzzle kombat. a good way to get a lot of koins thow is chess kombat and to annihilate the entire team. ull get a lot of koins that way.

It's Not that hard to beat Konquest I beat it in 2 days

yea, its just a matter of following the light!
