📍 Where to redeem: There is no web redemption page — redeem in game: open the menu (top right) → cog (top left) → Platform & Account → Redeem Code. Rewards arrive directly or by mail. The menu unlocks after the opening tutorial, and some codes such as ENDFIELD4PC are PC-only.
💡 How to redeem: There is no web page, so no [Redeem →] button. Copy the code and paste it in game under Settings → Platform & Account → Redeem Code. Each code works once per account and may expire without notice. Codes for the mainland China version do not work on the global version. Source: Pocket Tactics
