Koins are the main in-game currency in Mortal Kombat X. You earn Koins by completing Story Mode chapters, winning matches in any game mode (Towers, Versus, Online), and participating in Faction Wars. Koins are primarily used in The Krypt to unlock various chests and pathways, granting access to new costumes, fatalities, brutalities, and concept art. Accumulate as many as possible!
