MODERN WARFARE 4 (MW4) PARK HOLDS THE LINE CALLING CARD

WHO PARK IS Private Park Hyun-Jun is a South Korean Marine and one of the two playable leads in the Modern Warfare 4 campaign, played by Young Mazino. He is the figure at the centre of MW4's key art, and he is also unlockable as a base Operator by finishing the campaign. The calling card is tied to his story rather than to a battle pass or a store bundle.

WHERE IT COMES FROM, HONESTLY This card was handed out through a Call of Duty Discord Quest that opened on 16 October 2026 and closed on 7 November 2026. Accepting the quest and playing Modern Warfare 4 for fifteen minutes produced a redemption code. That is the only known source, which is why supply is finite once the quest closes. We would rather tell you that than let you find out afterwards. If the quest window is still open as you read this, go and claim it for free.

HOW REDEMPTION WORKS Sign in at callofduty.com/redeem with your own Activision account and enter the code. The card is added to the account, not to a single platform, so it follows you across Play Station, Xbox, PC and Switch 2. Codes are single use and bind to the first account that redeems them.

WHAT WE CANNOT PROMISE We are not an official Activision partner and we do not claim the card is available in every region. Discord quests are not offered everywhere. If a code does not redeem on your account, contact us and we will sort it out.
