Redeeming event coupons in PC FISH grants players access to limited decorations, promotional items, and crossover rewards without spending real currency. For broader tank progression strategies, see our beginner starter guide.

Coupon Code Menu and Settings Redemption

Developers at NANOO COMPANY introduced a dedicated redemption interface to simplify gift delivery. Following the September 11 update, players can access an Event Coupon option placed directly within Settings. Selecting this menu brings up a text dialogue where alphanumeric voucher keys can be submitted. Redeeming valid promotional codes immediately transfers bonus cosmetics into your active tank inventory.

Promotional Giveaways and the Mount Fuji Event

During Tokyo Game Show 2026, players who registered their email received an exclusive Mount Fuji decoration. That partnership event also provided three random Legendary items for sister title Tower of Babel: Survivors of Chaos. Earlier promotions featured a complimentary aquatic plant reward celebrating the official August 14 launch.

Managing Seasonal Variants and Merge Filters

Participating in limited-time events often rewards unique aquatic specimens alongside decorative novelties. To prevent accidental loss when combining duplicates, developers added an Exclude Seasonal Fish toggle to the Merge menu. Activating this safeguard ensures that Auto-Select filters bypass rare event breeds during fusion rituals.
