How to redeem codes

Codes in Murder Mystery Duo are redeemed through the in-game menu's code input field, likely found through a Codes button in the main HUD or lobby. Enter the code exactly as shown and confirm to claim your reward. The Cublix Games developer group wall and milestone announcement posts are the primary sources for new codes.

Code rewards include case boxes (Magic Box for mid-tier cosmetics, Space Box for space-themed weapon skins) and direct weapon cosmetics like the Royal Marble knife from the GOLD code. Case box rewards let players receive multiple random cosmetic items from the gacha-style opening system, making them more valuable per redemption than a single fixed reward.
