Marvel Contest of Champions is a mobile fighting game from Kabam where players build and upgrade rosters of Marvel heroes and villains for one-on-one combat, alliance wars, and special events. Promo codes can deliver free crystals, revives, energy refills, and even full champion characters directly to your in-game inbox, giving you a meaningful boost without spending units.

How to redeem Marvel Contest of Champions codes
Redemption happens through the web-based Summoner’s Market, not inside the game client directly. You’ll need a Kabam account linked to your in-game profile first — this can be set up from the Settings menu inside Marvel Contest of Champions.
Note: Beyond promo codes, daily and weekly free rewards — including crystals and gold — are available through the in-game shop on a recurring basis, so logging in regularly is worthwhile even when no active codes are running.
