Marvel Contest of Champions is a mobile and PC fighting game that pits Marvel’s heroes and villains against each other in one-on-one combat across a vast, ever-growing roster. Promo codes supply a range of free in-game items—crystals, revives, reunion crystals, and occasionally full champion unlocks—that can meaningfully speed up roster building without spending.

MCOC codes can expire without warning, so redeem these as soon as possible. Enter each code exactly as shown, since capitalization can affect whether a code is accepted.

How to redeem MCOC codes
Code redemption takes place through the Contest of Champions web store rather than directly inside the app. Before starting, make sure you have a Kabam account linked to your game profile—open the Settings menu in-game and follow the prompts to create or connect one.
Free daily and weekly rewards
The Contest of Champions shop page also offers free rotating rewards that refresh on daily and weekly schedules. These typically include crystals and gold, and checking in consistently to claim them adds up to a meaningful bonus over time—worth doing alongside any promo codes you redeem.
